Palladium-catalyzed C(sp3)—Si bonds transformation of commercially available polyalkoxy trifluorosilane reagents has been developed through C(sp3)—C(sp2) cross-coupling reactions. This Hiyama cross-coupling reaction shows good functional group tolerance and provides a series of trifluoropropyl (hetero)arenes. The fluoride source and alkyl tether of bisphosphine ligand play important roles in improving yields.

Key words: palladium catalysis, Hiyama cross-coupling reaction, fluoroalkylation, organosilicon
