新型金(Ⅰ)络合物的合成及其在催化炔烃与苯胺的氢胺化反应中的应用

Novel Gold(I)Complex:Synthesis and Its Application on Catalytic Hydroamination Reaction of Alkyne and Aniline

亚胺类化合物是十分重要的基础化工原料,通过开发高活性催化剂,催化苯炔与芳胺的氢胺化反应制备亚胺是一种有效的方法.论文利用二烷基烯锡与氯化金Au Cl键的插入反应,合成了一类新型烯锡配位的一价金络合物3.该一价金络合物表现出较强的“嗜碳性”,可以活化碳碳不饱和碳,从而实现苯胺与苯炔的氢胺化反应,高产率合成了亚胺类化合物.

Imines are very important basic chemical raw materials.The catalytic hydroamination reaction of alkyne and aniline is an important approach to prepare imines through developing highly active catalysts.In this study,a novel gold(I)complex with tin coordination was synthesized by insertion reaction of dialkylene tin with AuCl.This gold(I)complex exhibits strong'carbon affinity'and can activate unsaturated carbon.Thus,the ammonia hydrogenation reaction between aniline and phenylacetylene could be achieved,and imine compounds were synthesized with high yields.
