Oxidations of Thiourethanes, 10. - Synthesis, Crystal Structure, Oxidation and Photochemistry of Thione S-Oxides of Cyclic Dithiourethanes and DithiocarbazatesSeveral cyclic dithiocarbamates and dithiocarbazates (2-4) have been oxidised with mCPBA to give the corresponding thione S-oxides 5-7. The sulfine structure was confirmed by oxidation to the corresponding oxo derivatives and X-ray crystal structure analysis. Photolysis of the sulfines gave the corresponding oxo as well as the thioxo derivatives. The isolation of both the oxo and the thioxo derivatives is reported here for the first time, it provides an other evidence for the postulated thioxirane intermediate in the photolysis of sulfines.
