The Reductive Acylation of Organic Disulfides with Aldehydes under Photochemical and Radical Conditions
irradiation of organic disulfides in aldehyde solvents resulted in the reductive fission of the S–S linkage, giving an equimolar mixture of the corresponding thiol and the thiol acylate in a good yield. The cyclic disulfides gave mono S-acylated dithiols. The reaction proceeded by means of the photo-initiated radicalchainmechanism, and AIBN (azobisisobutyronitrile) effected the same reaction under thermal
