Nickel-catalyzed directed sulfenylation of sp2 and sp3 C–H bonds†
Abstract
Directed sulfenylation of both sp2 and sp3 C–H bonds was achieved through nickel catalyzed directed C–S bond formation, giving the desired product in good to excellent yield (up to 90%). Other metal cations, including Cu, Fe, Pd, Rh, Ru and Co, gave almost no reaction under identical conditions, which highlighted the unique reactivity of this Ni system.
