The synthesis and characterization of abnormal N-heterocyclic carbene, cyclic (alkyl)(amino)carbene, and mesoionic carbene copper(I) complexes are reported. These organometallic species are obtained via a versatile and inexpensive synthetic pathway using readily available reactants, namely copper oxide and iminium salts. The catalytic activity of this series of complexes was evaluated in the [3+2]
报道了异常N-杂环卡宾,环状(烷基)(氨基)卡宾和中离子卡宾铜(I)配合物的合成和表征。这些有机金属物质是通过通用且廉价的合成途径,使用容易获得的反应物,即氧化铜和亚胺盐获得的。在炔烃与叠氮化物(CuAAC)的[3 + 2]环加成中评估了这一系列配合物的催化活性。观察到异常的NHC和三偶氮亚烷基铜(I)配合物的杰出的催化性能。
