Abstract

Reported herein is a novel and sustainable electrochemical seleno-/tellurocyclization of propargyl carboxylic acids, affording a diverse range of valuable Se-/Te-incorporated unsaturated γ-lactones under ambient conditions. Preliminary mechanistic studies suggest that this transformation predominantly proceeds via a cationic pathway.
