Chalcogen bonding (ChB) has emerged as a promising tool in organic synthesis. However, compared with the well‐developed selenium‐ and tellurium‐based salt catalysts, the ChB catalysis of sulfonium salts is still unknown. Here, we report a new type of alkynyl‐sulfonium salt ChB catalysis for various...
