The combination of 1,4-benzoquinone and a catalytic amount of NaI was found to be effective for the deprotection of dithioacetals. The reactions proceeded efficiently under mild, near-neutral reaction conditions, producing a wide range of aryl and alkyl aldehydes and ketones generally in high yields with good functional group compatibility. The method developed therefore represents a general, facile, and highly applicable approach for deprotecting dithioacetals.

A novel class of pyronin analogues, which undergoes a photochemically induced cleavage of the C-C bond in the presence of water in both solution and on a silica gel surface upon direct irradiation with visible light, is reported. The reaction course can be monitored by characteristic fluorescence of both the starting compound and the final product. This system could find useful applications in the field of photoremovable protecting groups or caged fluorophores.

The kinetics of the reduction of cyclic disulphides with triphenylphosphine have been studied in aqueous ethanol at various temperatures.Solvent effects on the reaction of 4-phenyl-1,2-dithiolane with tris-(4-chlorophenyl) phosphine in a number of aqueous organic solvents have been analysed in terms of the Kirkwood, Y and ENT functions.
