A rhodium-catalyzed ylide formation/Smiles rearrangement reaction of chalcogenide ether and triazoles

摘要

A Rh(ii)-catalyzed highly stereoselective chalcogenide ylide formation/Smiles rearrangement reaction of diaryl thioether/selenoethers and triazoles was successfully developed, which provided an efficient strategy to construct trisubstituted acyclic vinyl sulfides/selenides. The salient features of this protocol include simple operation, readily available starting materials, atom economy, broad substrate scope, and convenient transformation of products.
