, p. 927 - 932 (2007/10/02)
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.Key Words: Dithio Esters / Thiono Esters / Thioamides / Azodicarboxylates / Azodicarboxamides / Trithiomesoxalamides
