摘要：

Disclosed herein is a dehydrosilylative difluoroamidation of alpha-Csp(3)-H of tetrahydroisoquinolines with alpha,alpha-difluoro-alpha-TMS-acetamides. The process, which occurs at ambient temperature in the absence of any transition metals, provides direct access to a broad range of alpha,alpha-difluoroacetamide-substituted tertiary amine derivatives in high yields. Moreover, the method was successfully applied in the Csp(3)-H-directed difluorophosphorylation and difluorocarboxylation under the same conditions.
