Iodine-promoted C(sp 2)–H methylthiolation of maleimides using DMSO as synthon has been developed to afford 3-methylthiomaleimides in moderate yields under metal-free conditions. In addition, 3-thiomaleimides were synthesized from maleimides and thiols in the presence of iodine and triethylamine. The methods are simple and efficient for the formation of C–Sbond.
