The activation of amines into thiocarbamoyl fluorides provides access to valuable nitrogen-based functionalities. Here, the authors report a mild, photochemical method for in-situ generation of thiocarbonyl difluoride from N-trifluoromethylthiophthalimide using visible light and organic reductants, and apply this strategy to the synthesis of azetidines from strained azabicyclo[1.1.0]butanes.
