An efficient alkylation method of functionalized alkyl halides under mild nickel‐catalyzed C(sp3)C(sp2) Suzuki cross‐coupling conditions is described. The features of this approach are excellent functional group compatibility, low cost nickel catalyst, and the use of a mild base. This is also the first successful example of the nickel‐catalyzed direct 2,2‐difluoroethylation or 2,2,2‐trifluoroethylation

A Cu-mediated trifluoromethylation of carbonyl-type compounds and unactivatedolefins enabled by visible-light irradiation via σ C(sp3)−C bond-functionalization has been developed. This protocol is characterized by its modularity, mild conditions and wide scope—even in the context of late-stage functionalization, thus offering a complementary approach en route to valuable C(sp3)−CF3 architectures from
