Direct thiolation of methoxybenzenes with thiols under metal-free conditions by iodine catalysis
摘要:
A direct thiolation of methoxybenzenes with various thiols has been developed. The protocol uses inexpensive reagents: catalytic iodine in the presence of DTBP. Importantly, no base or ligand was necessary. This method opens a new avenue to a variety of valuable thioethers that would be more difficult to access with traditional methods.

An odorless approach for arylthiolations of arenes is introduced, in which [Hmim]Br is used as both a solvent and a reducer.
