Oxidation of 1,3-cyclobutanedithiones (4-6) and 3-thio-1,3-cyclobutanediones (1-3) upon direct excitation and by singlet oxygen yields the corresponding sulfines and/or ketones.Formation of ketone is believed to involve 1,2,3-dioxathietane as the intermediate.A zwitterionic peroxide resulting from the interaction of singlet oxygen with thiocarbonyl chromophore is the common intermediate for both ketone and sulfine.The variation in the product distribution among 1-6 is understood on the basis of the electronic and steric factors operating on the zwitterionic peroxide intermediate.
