Photochemical electrocyclic ring closure and leaving group expulsion from N-(9-oxothioxanthenyl)benzothiophene carboxamides

N -(9-Oxothioxanthenyl)benzothiophene carboxamides bearing leaving groups (LG − = Cl − , PhS − , HS − , PhCH 2 S − ) at the C-3 position of the benzothiophene ring system photochemically cyclize with nearly quantitative release of the leaving group, LG − . The LG − photoexpulsions can be conducted w...
