An unprecedented type of reaction for Cu-catalyzed trifluoromethylation of terminal alkenes is reported. This reaction represents a rare instance of catalytic trifluoromethylation through C(sp(3))-H activation. It also provides a mechanistically unique example of Cu-catalyzed allylic C-H activation/functionalization. Both experimental and theoretical analyses indicate that the trifluoromethylation
报道了一种前所未有的铜催化末端烯烃三氟甲基化反应类型。该反应代表了通过 C(sp(3))-H 活化的催化三氟甲基化的罕见实例。它还提供了 Cu 催化的烯丙基 CH 活化/功能化在机械上独特的例子。实验和理论分析都表明三氟甲基化可能通过类 Heck 的四元环过渡态发生。
