Photo-reaction of lipoic acid and related organic disulphides: reductive acylation with aldehydes

Abstract
Irradiation of organic disulphides in aldehyde solvents resulted in reductive fission of the S–S linkage giving the corresponding thiol and an equimolar amount of the thiol acylate for linear disulphides and mono S-acylated dithiols for cyclic disulphides.
