Photooxidation of Leuco Dyes. XII. Time Resolved Investigations on the Photooxidation of Bis-sulfuric Acid Monoesters of Leucothioindigoid Compounds

The photooxidation of 4,4'-dimethyl-6,6'-dichlorothioindigosol (1) was studied by means of laser and conventional flash photolysis.Three transients were detected and assigned to a radical R generated by homolytic splitting of one O-S-bond of the parent compound and to two further radicals which are formed from R by hydrolytic cleavage of the second ester group.The latter two radicals are in a protolytic equilibrium with each other and react, depending on the nature of the solvent by H-atom abstraction, or by disproportionation forming the leuco-thioindigoid dye or bot h dye and leuco dye.A mechanistic scheme is proposed.
