N-Heterocyclic Carbene-Catalyzed Synthesis of Pentafluorophenyl Sulfides
An efficient method for the construction of C(sp2)—S bond has been developed.The stable N-heterocyclic carbene 1,3-bis(2,6-dissopropylphenyl)-imidazole-2-ylidene can activate the C—Si bond of pentafluorophenyl trimethylsilicon effectively to initiate the nucleophilic substitution reaction with thiosulfonic ester,producing pentafluorophenyl sulfide products in 34％～98％yields.
