Cu-Catalyzed tertiary alkylation of α-(trifluoromethyl)styrenes with tertiary alkylmagnesium reagents†
Abstract
A novel and efficient method for the synthesis of 3-tertiary alkylated 1,1-difluorostyrene derivatives via Cu-catalyzed alkylation of α-(trifluoromethyl)styrenes with tertiary alkylmagnesium reagents at room temperature was developed.
