h-BN@Copper(II) nanomaterial catalyzed cross-coupling reactions between sulfoximines and N-(phenylthio)-succinimide under mild condition

A novel and efficient method for the synthesis of NS substituted sulfoximines has been established with h-BN-supported copper(II) nanomaterial as the catalyst. Catalyzed by this heterogeneous catalyst, the desired products were obtained with wide scope of substrates, good to excellent yields, free ligand and low-toxicity solvent. Moreover, after being reused ten times, there is almost no significant loss of its catalytic activity.
