A DTBP-promoted, operationally simple, metal-free and solvent-free formation of C–Se and C–S bonds through sp3C–H functionalization of methyl arenes with diselenides and disulfides is described.
A DTBP-promoted C–H thiolation of aldehydes with disulfides under metal-free and solvent-free conditions is described. The system shows good functional group tolerance to afford thioesters in moderate to excellent yields.
