Planar chiral 2-(trifluoromethyl)quinoline-fused ferrocenes via palladium(0)-catalyzed C-H functionalization of trifluoroacetimidoyl chlorides

Catalytic enantioselective synthesis of planar chiral 2-(trifluoromethyl)quinoline-fused ferrocenes has been achieved through Pd(0)-catalyzed C-H functionalization with trifluoroacetimidoyl chlorides as electrophilics. With commercially available ligand and palladium precursor, the reaction proceeds smoothly generating 2-perfluoroalkylated quinoline-fused ferrocenes in high yields and enantioselectivities.
