Abstract: | On Chalcogenolates. 155. Reaction of N-Methyl Formamide with Carbon Disulfide. 2. N-Methyl N-Formyl Dithiocarbamic Acid and Oxidation of N-Methyl N-Formyl Dithiocarbamates The reaction of a solution of KS2C? NCH3? CO? H] in acetone-d6 with gaseous HCl at ?78°C forms unstable H? CO? NCH3? CS? SH. The existence of this acid in solution has been demonstrated by nuclear magnetic resonance spectra. The oxidation of N-methyl N-formyl dithiocarbamates with iodine yields N,N′-dimethyl N,N′-diformyl thiuram disulfide (H? CO? NCH3? CS? S? )2, which has been characterized by means of diverse spectroscopic methods. |
