Air promoted annulation of thiophenols with alkynes leading to benzothiophenes

Author affiliations

Abstract

Air promoted intermolecular annulation of thiophenols with alkynes, leading to complex benzothiophenes, is reported. This atom-economical reaction is performed in the absence of any catalyst, chemical oxidant and additive. Only a solvent and an air atmosphere were required. A plausible radical involved mechanism is proposed.
