✦ Synopsis

Dithio and Thiono Esters, 56. — Reaction of Thio Esters and Thio Amides with Azodicarboxylic Acid Derivatives

Dithio and thiono esters 1 react with azodicarboxylates 3 to form the addition products 4 or the oxidation products 5 in varying ratios. With malonates, malonamides and dithionomalonates only the addition products 7 were obtained. N,N,N′,N′‐Tetramethyldithiomalonamide yields with azodicarboxylic acid derivatives 3 either the normal addition product 8, the β‐elimination product 9 or N,N,N′,N′‐tetramethyltrithiomesoxalamide (10A), the first stable vicinal trithiocarbonyl compound.
