  • Synthetic, Structural, and Catalytic Studies of Well‐Defined Allyl 1,2,3‐Triazol‐5‐ylidene ( <i>tz</i> NHC) Palladium Complexes

    identical to those of the corresponding imidazole carbene palladium complexes, and that the tzNHC ligands have stronger donor properties than the imidazole carbene ligands. The relationship between catalytic activity and structure was examined by carrying out a room-temperature Suzuki–Miyaura coupling reaction, and the cinnamylpalladium complex bearing 1,4-bis(2,6-diisopropylphenyl)-3-methyl-1,2,3-triazol-5-ylidene
    制备了一系列烯丙基 1,2,3-三唑-5-亚基 (tzNHC) 配合物,并通过 NMR 和 X 射线衍射分析充分表征了配合物的结构。通过研究它们的羰基铱配合物的振动光谱和它们的 X 射线光电子光谱来评估这些配体的供体性质。这些评价表明,tzNHC 配合物的结构与相应的咪唑卡宾配合物的结构几乎相同,并且 tzNHC 配体咪唑卡宾配体具有更强的供体性质。通过进行室温 Suzuki-Miyaura 偶联反应和带有 1,4-双(2,6-二异丙基苯基)-3-甲基-1,2 的肉桂基配合物,研究了催化活性和结构之间的关系,发现 3-三唑-5-亚基 (TPr) 是活性最高的催化剂。无论取代基的电子和空间性质如何,(肉桂基)(TPr)PdCl 在与芳基化物进行的室温反应中都表现出高活性,并且在与空间拥挤的芳基硼酸反应中有效。
  • Copper(I) Complexes of Mesoionic Carbene: Structural Characterization and Catalytic Hydrosilylation Reactions

    Two series of different Cu(I)-complexes of “click” derived mesoionic carbenes are reported. Halide complexes of the type (MIC)CuI (with MIC = 1,4-(2,6-diisopropyl)-phenyl-3-methyl-1,2,3-triazol-5-ylidene (for 1b), 1-benzyl-3-methyl-4-phenyl-1,2,3-triazol-5-ylidene (for 1c)) and cationic complexes of the general formula [Cu(MIC)2]X (with MIC =1,4-dimesityl-3-methyl-1,2,3-triazol-5-ylidene, X = CuI2− (for 2á), 1,4-dimesityl-3-methyl-1,2,3-triazol-5-ylidene, X = BF4− (for 2a), 1,4-(2,6-diisopropyl)phenyl-3-methyl-1,2,3-triazol-5-ylidene, X = BF4− (for 2b), 1-benzyl-3-methyl-4-phenyl-1,2,3-triazol-5-ylidene, X = BF4− (for 2c)) have been prepared from CuI or [Cu(CH3CN)4](BF4) and the corresponding ligands, respectively. All complexes were characterized by elemental analysis and standard spectroscopic methods. Complexes 2á and 1b were studied by single-crystal X-ray diffraction analysis. Structural analysis revealed 2á to adopt a cationic form as [Cu(MIC)2](CuI2) and comparison of the NMR spectra of 2á and 2a confirmed this conformation in solution. In contrast, after crystallization complex 1b was found to adopt the desired neutral form. All complexes were tested for the reduction of cyclohexanone under hydrosilylation condition at elevated temperatures. These complexes were found to be efficient catalysts for this reaction. 2c was also found to catalyze this reaction at room temperature. Mechanistic studies have been carried out as well.

    3-triazolylidene-based mesoionic carbene (MIC) gold complex with a weakly coordinating second ligand. In contrast to expectations, the gold complexes bearing the most strongly electron donating MICs did not display the best conversion in catalysis. According to our investigations the stability of the complex is a determining factor in the present case. The MIC gold bistriflimide complex shows activity in hydroamination
    通过配体设计控制催化性能是均相催化的核心。本文中,我们报道了六种1,3,4-取代的1,2,3-三唑基亚配合物中的配体效应,这些配合物是炔烃与胺的分子间加氢催化的前催化剂。配合物的合成和催化反应主要遵循无方案。据我们所知,所有新型络合物均已得到充分表征,其中之一是具有弱配位的第二个配体的第一个1,2,3-三唑基亚甲基中离子卡宾(MIC)络合物。与预期相反,带有最强电子给体MIC的络合物在催化方面没有表现出最佳的转化率。根据我们的研究,在当前情况下,配合物的稳定性是决定性因素。MIC杀虫双络合物无需加助剂即可在加氢胺催化反应中显示出活性。
