摘要：
Herein, we report a protocol for direct visible-light-mediated C-I difluoroallylation reactions of a-trifluoromethyl arylalkenes with alkyl iodides at room temperature with an alpha-aminoalkyl radical as a mediator. The protocol permits efficient functionalization of various alpha-trifluoromethyl arylalkenes with cyclic and acyclic primary, secondary, and tertiary alkyl iodides and is scalable to the gram level. This mild protocol uses an inexpensive mediator and is suitable for late-stage functionalization of complex natural products and drugs.
