N-heterocyclic carbenes (NHCs) was uncovered as an efficient ligand in promoting allylic C-H bond functionlizations. Notably, the catalytic [Pd(eta(3)-cin)(IPr)Cl] complex (where cin = cinnamyl) was formed in situ from direct CH activation of allylic precursors, and was obtained by way of one-pot strategy with available IPr.HCl and allylbenzene. The catalyst exhibits high regioselectivity and stereoselectivity of the allylic C-H alkylation with oxindoles with a broad scope.
