The N-acylation of a sulfoximine with carboxylic acids was accomplished with boric acid and several boronic acids. Aliphatic acids give fair yields of products while acids related to phenylacetic and phenoxyacetic acids perform much better. Aromatic acids are ineffective in this process.

The electrochemical synthesis of N-aroylsulfoximines features the use of tetra-n-butylammonium iodide (TBAI) as the medium and a broad substrate scope, thus affording a wide range of N-aroylated sulfoximines in moderate to good yields. The advantages of this electrochemical strategy are augmented by mild reaction conditions that are external oxidant-free, ligand-free, and easy to scale up to gram scale
