Synthesis and Photolysis of 4-Thioxoazetidin-2-ones
3,3-Diphenyl-4-thioxoazetidin-2-ones have been synthesized by photocyclisation of N-diphenylacetylthiocarbamates, and 3-phenyl-4-thioxoazetidinones have been prepared by thionation of azetidine-2,4-diones.Photolysis of the 3,3-diphenyl derivatives in meth
