Abstract
Benzynes react with allylic acetates or halides and terminal alkynes in the presence of Pd(PPh3)4, CuI and CsF in CH3CN at 50 degrees C for 5 h to give 1-allyl-2-alkynylbenzene derivatives in good to excellent yields.
摘要
在50℃下，苯炔在乙腈中，于Pd(PPh3)4、CuI和CsF存在的情况下，与烯丙基乙酸酯或卤化物以及末端炔烃反应5小时，以良好至优异的产率生成1-烯丙基-2-炔基苯衍生物。
