Heteroaryl thioethers, especially alkyl heteroaryl thioethers, were usually obtained by catalytic or non-catalytic coupling reactions under strong basic conditions, but these methods usually have many drawbacks such as generation of large amounts of wastes. In this work, a new method for the direct synthesis of N-heteroaryl thioethers through a base-, additive-, and solvent-free one-pot multi-component reaction of N-heteroaryl halides, thiourea, and alkyl bromides was reported. This method can employ thiourea as the sulfur surrogate and tolerate various alkyl bromides and N-heteroaryl halides, providing a concise, selective, and efficient new method for heteroaryl thioether synthesis.

Key words: N-heteroaryl thioethers, base-free, thiourea, sulfur transfer, multi-component reaction
