在三氟乙酸存在下,在二氯甲烷中,在没有任何金属催化剂或添加剂的情况下,进行了芳基取代炔与简单芳烃和取代芳烃的氢芳基化反应。富电子芳烃与芳基取代的炔偶联,以良好到高产率得到1,1-二芳基烯烃。
Hydroarylation of aryl-substituted alkynes with simple and substituted arenes was conducted in the presence of trifluoroacetic acid in dichloromethane without any metal catalysts or additives. Electron-rich arenes coupled with aryl-substituted alkynes to give 1,1-diarylalkenes in good to high yields.
