A mild and regioselective method for the preparation of unsymmetrical biaryl sulfides using iron(III) catalysis is described. Activation of N-(arylthio)succinimides using the powerful Lewis acid iron(III) triflimide allowed the efficient thiolation of a range of arenes, including anisoles, phenols, acetanilides, and N-heterocycles. The method was applicable for the late-stage thiolation of tyrosine and tryptophan derivatives and was used as the key step for the synthesis of pharmaceutically relevant biaryl sulfur-containing compounds such as the antibiotic dapsone and the antidepressant vortioxetine. Kinetic studies revealed that while N-(arylthio)succinimides bearing electron-deficient arenes underwent thioarylation catalyzed entirely by iron(III) triflimide, N-(arylthio)succinimides with electron-rich arenes displayed an autocatalytic mechanism promoted by the Lewis basic product.

A novel and efficient method for the synthesis of N-S 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.
