Palladium-catalyzedallylic C−H silylation was performed with use of hexamethyldisilane as the silyl source. These C−H functionalization reactions occur only in the presence of hypervalent iodine reagents or other strong oxidants and proceed with excellent regioselectivity, providing the linear allylic isomer of the allylsilane products. In demonstrating the first oxidative allylic C−H silylation of
A direct and simple catalytic coupling of nonfluorinated and fluorinated silylbutenamides with β-CF3 α,β-unsaturated esters mediated by fluorideion was carried out. The transformation proceeded with excellent yields to afford new, highly functionalized trifluoromethylated and quaternary fluorinated products.
