THE PHOTOLYSIS OF 1,3,4-THIADIAZOLIDINE-2,5-DITHIONES IN PRESENCE AND IN ABSENCE OF SINGLET OXYGEN

The photolysis of 1,3,4-thiadiazolidine-2,5-dithiones (Ia-c) in methanol has been studied.The disulphides IIa-c were isolated and identified.Dye sensitized photooxygenation of compounds Ia-c were also studied.Compounds IIa, IIIa and IVa were produced in case of Ia, and IIb and IIIb were produced in Ib, and IIc and IIIc were produced in Ic.A mechanism for the formation of these compounds is presented.
