Tetradentate ONNO donor ligands H2hz(fp)2 (I), H2hz(butp)2 (II) and H2hz(bp)2 (III) synthesized by the reaction of hydrazine hydrate with 4‐formyl‐3‐methyl‐1‐phenyl‐5‐pyrazolone (fp), 4‐butyryl‐3‐methyl‐1‐phenyl‐5‐pyrazolone (butp) and 4‐benzoyl‐3‐methyl‐1‐phenyl‐5‐pyrazolone (bp), respectively, react with [MoVIO2(acac)2] in 1:2 molar ratio in refluxing methanolic to give binuclear complexes [(μ‐O){MoVIO2(H2O)}2hz(fp)2] (1) and [(μ‐O){MoVIO2(H2O)}2hz(butp)2] (2) and [(μ‐O){MoVIO2(H2O)}2hz(bp)2] (3). All ligands and complexes are characterized by several techniques that include, FT‐IR, UV‐Vis, 1H NMR, 13C NMR spectroscopy, elemental and thermal analysis and single crystal X‐ray analysis of 2 and 3. Ligands coordinate through a set of ON functionalities of the same ligand to two MoVIO2 groups attached through an oxido‐bridge. Additional coordination of water making them to maintain an octahedral geometry. Azine moiety coordinates to two molybdenum through the symmetrical µ‐{ƞ2‐(N–N)} fashion. Catalytic activity of these complexes was studied for the cycloaddition of CO2 with epoxides. A pressure of 20 bar CO2, 3.0 mg catalyst, 1 mmol of tetrabutylammonium bromide (TBAB) at 120 °C for 6 h were found to be most suited reaction condition for 5 mmol epoxide. Under the optimized reaction conditions, the product yield and selectivity of alkene carbonate for all complexes were investigated. As high as 96% yield with almost 99% selectivity for styrene carbonate.
四价 ONNO 给体配体 H2hz(fp)2 (I)、H2hz(butp)2 (II) 和 H2hz(bp)2 (III) 由肼水合物与 4-甲酰基-3-甲基-1-苯基-5-吡唑酮(fp)反应合成、4-丁酰基-3-甲基-1-苯基-5-吡唑酮(butp)和 4-苯甲酰基-3-甲基-1-苯基-5-吡唑酮(bp)分别与[MoVIO2(acac)2]以 1:2 摩尔比在回流甲醇中反应,得到双核配合物 [(μ-O){MoVIO2(H2O)}2hz(fp)2](1)和 [(μ-O){MoVIO2(H2O)}2hz(butp)2](2)以及 [(μ-O){MoVIO2(H2O)}2hz(bp)2](3)。所有配体和配合物均采用多种技术进行表征,包括傅立叶变换红外光谱、紫外可见光谱、1H NMR、13C NMR 光谱、元素和热分析,以及 2 和 3 的单晶 X 射线分析。配体通过一组相同配体的 ON 官能团与两个通过氧化桥连接的 MoVIO2 基团配位。水的额外配位使它们保持八面体几何形状。氮分子通过对称的 µ-{ƞ2-(N-N)} 方式与两个钼配位。研究了这些配合物在 CO2 与环氧化物环加成反应中的催化活性。研究发现,20 bar CO2 的压力、3.0 mg 催化剂、1 mmol 四丁基溴化铵 (TBAB)、120 °C、6 h 是最适合 5 mmol 环氧化物的反应条件。在优化的反应条件下,研究了所有配合物的产物产率和碳酸烯烃的选择性。碳酸苯乙烯的产率高达 96%,选择性接近 99%。

The Cover Feature shows a general structure of p-block and transition metal compounds, supported by sulfur-based ligands like SacSac, AcSac, SacNac and related ligands. In the last decade, a “re-emerging age” of this chemistry has been based mainly on the use of Lawesson's reagent as a mild sulfur-source for the ligand's synthesis. The beautiful nature of monarch butterflies (Danaus plexipus) and geothermal sulfurated waters (Los Azufres, Michoacán, México) resemble our efforts to spread this chemistry to different research fields.

Air‐stable cyclometalated palladium(II) complexes with benzamide ligands were synthesized in high yields and characterized by X‐ray diffraction analysis, CVA, 1H NMR, 13C NMR spectroscopy, MALDI‐MS, and ESI‐MS. The electrochemical oxidation of the complexes is reversible in the presence of a quinoline substituent in the ligand and gives Pd (III) species that do not undergo reductive elimination and are detectable by ESR spectroscopy. The complexes showed high cytotoxicity against cervical cancer (M‐HeLa) and duodenal adenocarcinoma (HuTu 80), a human mammary ductal adenocarcinoma line (MCF‐7) and a human lung carcinoma cell line (A549). The possibility of generating reactive oxygen species in solution (such as OH‐radicals), which can be responsible for the antitumour activity of the studied complexes, using the ESR method was shown.

Complexation of ThoriumIV with Fluorinated Heterocyclic β‐Diketones in Aqueous Hydrochloric Solutions 钍IV与含氟杂环β-二酮类化合物在盐酸水溶液中的络合反应

The interaction of Thorium(IV) with a group of non‐symmetric CF3‐diketones has been studied by means of electronic absorption spectroscopy in HCl aqueous solutions at I=0.5 M (NaCl) and T=298 K. Six heterocyclic dicarbonyl ligands (2‐thenoyl‐trifluoroacetone, 2‐furoyl‐trifluoroacetone, 2‐selenophen‐trifluoroacetone, 2‐tellurophen‐trifluoroacetone, phenyl‐trifluoroacetone, and 2‐naphthyl‐trifluoroacetone) demonstrate the chelation activity toward ThIV in the acidic pH range. Obtained values of the “true” stability constants lie in the range 6.2‐6.8 logarithmic units, respectively. A significant (10‐15 nm) bathochromic shift between the maximum absorption wavelength of lanthanide and actinide monocomplexes has been detected. Observed spectral shift increases with the atomic number of substituted chalcogen atoms in the heterocyclic ring of the corresponding ligand: 10 nm for furan, 11 nm for thiophen, 14 nm for selenophen, and 15 nm for tellurophene rings. The complexation with Thorium occurs in an acidic media, where studied ligands do not interact with transition and rare earth metals. Spectral and pH shifts make studied ligands useful reagents for the detection and analytical determination of Thorium in the mixture with other metals without prior separation. Quantum‐chemical simulations (DFT and TD‐DFT) demonstrate that the nine‐ and deco‐coordinated structures of ThoriumIV complexes reproduce experimental values within reasonable errors.
在 I=0.5 M(NaCl)和 T=298 K 的盐酸水溶液中,通过电子吸收光谱研究了钍(IV)与一组非对称 CF3-二酮的相互作用。六种杂环二羰基配体(2-苯甲酰基-三氟丙酮、2-呋喃基-三氟丙酮、2-硒吩-三氟丙酮、2-碲吩-三氟丙酮、苯基-三氟丙酮和 2-萘基-三氟丙酮)在酸性 pH 值范围内对 ThIV 具有螯合活性。获得的 "真实 "稳定常数值分别为 6.2-6.8 对数单位。在镧系元素和锕系元素单复合物的最大吸收波长之间发现了明显的(10-15 nm)浴色偏移。观察到的光谱偏移随相应配体杂环中取代的查耳根原子的原子序数增加而增加:呋喃为 10 纳米,噻吩为 11 纳米,硒吩为 14 纳米,碲环为 15 纳米。与钍的络合发生在酸性介质中,所研究的配体在酸性介质中不会与过渡金属和稀土金属发生作用。光谱和 pH 值的变化使所研究的配体成为检测和分析确定钍与其他金属混合物的有用试剂,而无需事先分离。量子化学模拟(DFT 和 TD-DFT)表明,钍-IV 复合物的九配位和十配位结构在合理误差范围内再现了实验值。

This work presents the synthesis and full characterization of Pd(II)‐butadienyl complexes incorporating picolyl‐NHC or phosphine ligands (PPh3 or PTA). These complexes were evaluated against four different cancer cell lines and human lung fibroblasts. Our findings indicate a slightly lower antiproliferative activity of picolyl‐NHC Pd(II)‐butadienyl complexes compared to recently published ones featuring N‐N, P‐P, and C‐C ligands but, above all, they exhibited selectivity for ovarian cancer cells. Additionally, trans‐[PdX (phosphine)2C4(COOMe)4Y)] derivatives (X = Br, Cl and Y = CH3, Br) proved excellent anticancer activity across all tested cancer cell lines, especially the bisPTA complexes. Importantly, the IC50 values suggest minimal impact from the halide coordinated to palladium or that present in the butadienyl terminal position. Furthermore, the low activity observed towards non‐cancerous cells underscores the potential of these synthesized Pd(II)‐butadienyl compounds as promising candidates for further investigation in anticancer research.
本研究介绍了含有吡啶-NHC 或膦配体(PPh3 或 PTA)的钯(II)-丁二烯基配合物的合成和全面表征。我们针对四种不同的癌细胞系和人肺成纤维细胞对这些配合物进行了评估。我们的研究结果表明,与最近发表的具有 N-N、P-P 和 C-C 配体的皮醇-NHC Pd(II)-butadienyl 复合物相比,皮醇-NHC Pd(II)-butadienyl 复合物的抗增殖活性略低,但最重要的是,它们对卵巢癌细胞具有选择性。此外,反式-[PdX(膦)2C4(COOMe)4Y)]衍生物(X = Br、Cl 和 Y = CH3、Br)在所有测试的癌细胞系中都表现出卓越的抗癌活性,尤其是双 PTA 复合物。重要的是,IC50 值表明,与钯配位的卤化物或存在于丁二烯末端位置的卤化物的影响极小。此外,观察到的对非癌细胞的低活性也强调了这些合成的 Pd(II)-丁二烯基化合物作为候选化合物在抗癌研究中进行进一步研究的潜力。

Furthermore, the low activity observed towards non‐cancerous cells underscores the potential of these synthesized Pd(II)‐butadienyl compounds as promising candidates for further investigation in anticancer research.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.524,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141585963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lanthanide (Ln) elements are critical materials that are typically extracted/mined together. Their separation by solvent extraction from acidic media is well known; however, there are few studies in basic media with carbonate anions. We investigated the complexation of Eu(III) and Tb(III) carbonates as solids and solutions in alkaline K2CO3, wherein we sought to access a Tb(IV) carbonate complex through ozonolysis. L3‐edge XANES of Eu and Tb carbonate solids, colorless solutions, and a red‐hued Tb solution (obtained by ozonolysis) all showed Ln(III) cations. The absence of evidence for a Tb(IV) complex was confirmed through XAS and EPR analyses, despite the solution exhibiting a deep red color. For solids and solutions, EXAFS results indicate molecular Ln(III)‐carbonato anions. In terms of the Eu(III) carbonate coordination number, the coordination does not change upon dissolution of the solid sample. Furthermore, EXAFS for the solutions revealed evidence for the association of potassium cations with the Ln(III)‐carbonato anions. This direct observation of contact ion pairing by EXAFS at room temperature is rare. The insights into Ln(III) carbonate complexation and solution speciation afforded by XANES‐EXAFS, FT‐IR, and EPR provides perspectives that serve as benchmarks for future computational and experimental efforts focused on caustic‐side solvent extraction of Ln(III) ions.
镧系元素(Ln)是通常一起提取/开采的关键材料。通过溶剂萃取法从酸性介质中分离镧系元素已是众所周知的事情,但在含有碳酸盐阴离子的碱性介质中分离镧系元素的研究却很少。我们研究了 Eu(III)和 Tb(III)碳酸盐在碱性 K2CO3 固体和溶液中的络合情况,并试图通过臭氧分解获得 Tb(IV)碳酸盐络合物。Eu 和 Tb 碳酸盐固体、无色溶液和红色 Tb 溶液(通过臭氧分解获得)的 L3 边 XANES 均显示出 Ln(III) 阳离子。尽管溶液呈现出深红色,但通过 XAS 和 EPR 分析证实没有证据表明存在锑(IV)络合物。对于固体和溶液,EXAFS 结果表明存在分子 Ln(III)- 碳酸阴离子。就 Eu(III)碳酸根的配位数而言,固体样品溶解后配位并没有改变。此外,溶液的 EXAFS 显示了钾阳离子与 Ln(III)- 碳酸根阴离子结合的证据。这种在室温下通过 EXAFS 直接观察到接触离子配对的现象非常罕见。通过 XANES-EXAFS、FT-IR 和 EPR 对 Ln(III)碳酸根的络合和溶液分型的深入了解,为今后计算和实验萃取 Ln(III)离子的苛性钠侧溶剂提供了基准。

Metal dihydride dihydrogen‐derived intermediates can be short‐lived and difficult to detect despite their ubiquitous role in chemical transformations such as hydrogenation. Here, highly reactive [Ir(H)3(η2‐η2‐COD)(IMes)] forms by trapping [Ir(H)2(η2‐H2)(η2‐η2‐COD)(IMes)]X [X = Cl or MeO], resulting from reaction of [IrCl(η2‐η2‐COD)(IMes)] with a base and H2. This trihydride allows access to the unusual [Ir2(H)4(OMe)(IMes)2(pyridine)3]X, [Ir2(H)2(µ2‐H)2(η2‐η2‐COD)(IMes)2], [Ir3(H)9(IMes)3], [Ir4(H)12(IMes)4] and [Ir2(H)4(µ2‐H)2(IMes)2(pyridine)2]. A combination of 2D NMR, parahydrogen hyperpolarized NMR, MS, and XRD are used to characterise these reaction products and rationalise their formation via the moiety {Ir(H)3(IMes)}. Consequently, the results of these studies have implications for iridium‐catalyzed polarization transfer from parahydrogen via the well‐known precursor [IrCl(η2‐η2‐COD)(IMes)].
尽管金属二酐二氢衍生中间体在氢化等化学转化过程中的作用无处不在,但它们的寿命很短且难以检测。在这里,高活性的[Ir(H)3(η2-η2-COD)(IMes)]通过捕集[Ir(H)2(η2-H2)(η2-η2-COD)(IMes)]X [X = Cl 或 MeO]而形成,它是由[IrCl(η2-η2-COD)(IMes)]与碱和 H2 反应生成的。通过这种三酸酐可以得到不常见的 [Ir2(H)4(OMe)(IMes)2(吡啶)3]X、[Ir2(H)2(μ2-H)2(η2-η2-COD)(IMes)2]、[Ir3(H)9(IMes)3]、[Ir4(H)12(IMes)4] 和 [Ir2(H)4(μ2-H)2(IMes)2(吡啶)2]。我们结合使用了二维核磁共振、对氢超极化核磁共振、质谱和 XRD 来描述这些反应产物的特征,并通过分子 {Ir(H)3(IMes)} 来合理解释它们的形成。因此,这些研究结果对铱催化对氢通过著名的前体[IrCl(η2-η2-COD)(IMes)]进行极化转移具有重要意义。

Organotellurium(II) and ‐(IV) Compounds with Picolinoylbis(thio­ureas): From Simple 1:1 Adducts to Multimetallic Aggregates 有机碲(II)和-(IV)与吡啶酰双(硫脲)化合物:从简单的 1:1 加合物到多金属聚集体

Reactions of 2,6‐dipicolinoylbis(N,N‐diethylthiourea) (H2LEt) with common tellurium(IV) starting materials such as PhTeBr3 or TeBr4 yield various tellurium(IV) and tellurium(II) compounds depending on the conditions applied. Equimolar amounts of H2LEt and PhTeBr3 give the 1:1 complex [PhTeIVBr3(H2LEt)], while with an excess of H2LEt, the tellurium compound is partially reduced and a {PhTeII}+ building block coordinates to both sulfur atoms of H2LEt under formation of the ion pair [PhTeII(H2LEt)][PhTeIVBr4]. Similar reactions between H2LEt and TeBr4 give the neutral monomer [TeIIBr2(H2LEt)] or the coordination polymer [TeIIBr2(H2LEt)]∞. The latter compound is also formed with the assistance of Pb2+ ions. While the lead ions do not appear in the isolated product, similar reactions with transition metal ions such as Ni2+, Mn2+, or Co2+ result in the formation of hetero­bimetallic complexes, in which Te(II) building blocks are directed to the sulfur atoms of the deprotonated ligand {H2LEt2‐S,S}2‐, while the transition metal ions occupy central coordination positions between two of the organic ligands using the pyridine nitrogen atom, carbonyl oxygen atom(s) and/or the nitrogen atoms of the thiourea units.
2,6-二二olinoylbis(N,N-二乙基硫脲) (H2LEt) 与常见的碲(IV)起始材料(如 PhTeBr3 或 TeBr4)发生反应,会产生各种碲(IV)和碲(II)化合物,这取决于所应用的条件。等摩尔量的 H2LEt 和 PhTeBr3 会生成 1:1 的复合物 [PhTeIVBr3(H2LEt)],而当 H2LEt 过量时,碲化合物会被部分还原,{PhTeII}+ 构建块配位到 H2LEt 的两个硫原子上,形成离子对 [PhTeII(H2LEt)][PhTeIVBr4]。H2LEt 和 TeBr4 之间的类似反应会产生中性单体 [TeIIBr2(H2LEt)] 或配位聚合物 [TeIIBr2(H2LEt)]∞。后一种化合物也是在 Pb2+ 离子的帮助下形成的。虽然铅离子不会出现在分离产物中,但与过渡金属离子(如 Ni2+、Mn2+ 或 Co2+)的类似反应会形成杂多金属配合物,其中 Te(II)结构单元与去质子化配体 {H2LEt2-S、S}2-,而过渡金属离子则利用吡啶氮原子、羰基氧原子和/或硫脲单元的氮原子占据两个有机配体之间的中心配位。
