N-杂环卡宾已经成为金属有机化学、无机配位化学等领域广泛使用的优良配体,尤其是其过渡金属配合物在催化领域中取得了丰硕的成果。其中N-杂环卡宾铜配合物的相关报道虽然出现较晚,但相比于含Ru、Pd等贵金属催化剂及以有机膦为配体的过渡金属配合物,其不仅有价格低廉、低毒等优势,还在共轭加成、[3+2]环加成等反应中表现出优良的催化活性,成为目前的研究热点。本文总结了近年来N-杂环卡宾铜配合物在催化领域中的研究进展。 N-heterocyclic carbenes have been widely used as ligands in metal-organic chemistry and inorganic coordination chemistry. In particular, their transition metal complexes have achieved fruitful results in the field of catalysis. The related reports of N-heterocyclic carbene copper complexes appear late, but compared with precious metal catalysts containing Ru, Pd and other transition metal complexes with organic phosphine as ligand, they are not only cheap, low toxicity and other It has also become a research hotspot in the reactions of conjugate addition, [3 + 2] cycloaddition and other reactions. This review summarizes recent advances in the field of catalysis of N-heterocyclic carbene copper complexes.
