An efficient C(sp3)–CF3 bond-forming reaction via Cu-catalyzed oxidative trifluoromethylation of terminal alkenes has been developed, which proceeds under mild conditions using readily available, less expensive CF3SiMe3 as the source of the CF3 group. This method allows access to a variety of trifluoromethylated allylic compounds.

A silver bullet: The title reaction results in selective formation of trifluoromethylated alkanes, and is in contrast to the previously reported transition‐metal‐catalyzed trifluoromethylation of olefins to generate a series of trifluoromethylated allylic compounds. Preliminary mechanistic investigations indicate that the current hydrotrifluoromethylation proceeds through a pathway involving a CF3
