A carbonylative cyclization of propargylic amines with elemental selenium to produce (E)‐5‐(iodomethylene)‐1,3‐selenazolidin‐2‐ones has been developed for the first time. Using DBU as the promoter and n‐C4F9I as the iodide source, various target compounds were produced up to 95 % yields. Notably, benzene‐1,3,5‐triyl triformate (TFBen) was employed as a safe and convenient solid CO source here. A new and straightforward carbonylation procedure toward (E)‐5‐(iodomethylene)‐1,3‐selenazolidin‐2‐ones has been established for the first time. By using DBU as the promoter, propargylic amines and elemental selenium were carbonylatively cyclized with TFBen as the CO source using n‐C4F9I as the iodide source. Various desired products with broad functional groups are synthesized in up to 95 % yields under mild conditions. [ABSTRACT FROM AUTHOR]
