The synthesis of gem-1,3-enynes via Ni/Cu-catalyzed decarboxylative addition of alkynoic acids to terminal alkynes has been developed. It was found that the decarboxylation of an alkynoic acid led predominantly to gem-1,3-enynes instead of 1,3-diynes, which have been known to be formed through the coupling of terminal alkynes. A variety of gem-1,3-enynes were obtained in good yields. This catalytic
的合成宝石通过镍/铜催化的脱羧加入alkynoic酸以末端炔-1,3-烯炔已经研制成功。已经发现,一个alkynoic脱羧主要导致宝石-1,3-烯炔,而不是1,3-二炔,它已经知道通过末端炔烃的联接而形成。以高收率获得了多种宝石-1,3-烯炔。该催化体系表现出优异的区域选择性和高官能团耐受性。
