Two practical and complementary methods are reported for the synthesis of trifluoromethylated alkynes. The first one, a mix‐and‐stir process, is based on the oxidative trifluoromethylation of readily available and bench‐stable copper acetylides while the second one, which displays a broad substrate scope and has several advantages over existing procedures, is based on the oxidative copper‐catalyzed
报道了两种实用和互补的方法用于合成三氟甲基化炔烃。第一种是混合搅拌法,基于易得的和板凳稳定的乙炔铜的氧化三氟甲基化,而第二种基于较广泛的底物范围,并且与现有方法相比具有多个优点,其基础是末端炔烃的氧化铜催化直接三氟甲基化。两种反应均提供了用户友好的三氟甲基化乙炔的合成方法,该方法可轻松地从容易获得的起始原料中获得。
