末端炔烃二聚反应合成共轭烯炔的研究进展

Progress in Dimerizations of Terminal Alkynes to Synthesize Enynes

综述了不同催化体系催化末端炔烃二聚反应合成共轭烯炔化合物的研究进展.其中催化体系主要包括过渡金属配合物、镧系和锕系金属配合物、第三主族元素配合物以及有机催化剂.实验结果表明:不同催化体系对末端炔烃二聚反应的选择性控制有影响,尤其是区域选择性(头-头二聚或头-尾二聚).

Progress in a variety of catalytic systems-catalyzed dimerizations of terminal alkynes to synthesize enynes is summarized. These catalytic systems included transition-metal complexes, organolanthanide and organoactinium complexes, IliA element complexes and organic catalysts. The results showed that the catalytic systems had a fundamental influence on the selectivity, in particular regioselectivity （head-to- head or head-to-tail）, of the dimerization reactions of terminal alkynes.
