I/DMSO-mediated oxidative C-C and C-heteroatom bond formation: a sustainable approach to chemical synthesis.

The I/DMSO pair has emerged as a versatile, efficient, practical, and eco-friendly catalyst system, playing a significant role as a mild oxidative system, and thus employed as a good alternative to metal catalysts in synthetic chemistry. Presently, I/DMSO is a thriving catalytic system that is used in preparing C-C and C-X (X = O/S/N/Se/Cl/Br) bonds, resulting in the formation of various bioactive molecules. Many processes utilize this system, including glyoxal synthesis by diverse sp, sp, and sp functionalities iodination and subsequent Kornblum oxidation.
