Cerium-mediated conjugate additions of (diethoxyphosphinoyl)difluoromethyllithium to cyclic vinyl sulfones proceeded smoothly; reduction afforded the products of formal alkylation, attaching the difluoromethylene phosphonate group to a secondary carbon atom. With acyclic vinyl sulfones, the addition was considerably less efficient and deprotonation competed with addition. Addition failed completely in the absence of cerium(III) chloride.
