Abstract A new approach for the one‐pot synthesis of alkynyl chalcogenides, exemplified mainly by selenides, was developed in which dual activation diorgano dichalcogenides and terminal acetylenes is achieved using an indium(III) catalyst. The method has advantages broad substrate scope, simple operation, mild reaction conditions, good yields. plausible mechanism proposed.
