PHENYLTHIOCARBAMIDES. A CONTRIBUTION TO THE STUDY OF THE TRIAD-N - C. S- PART XI. OXIDATION OF PHENYLTHIOCARBAMIDE WITH COPPER SULPHATE, CUPRIC CHLORIDE, COPPER NITRATE, FERRIC CHLORIDE AND IODINE.

Copper sulphate and cupric chloride have been found to be reduced by pheaylthio­carbamide in acid medium with the simultaneous formation of complexes of the reduced salts. The reaction consists of two stages, primary and secondary. Primary reaction is independent of temperature, concentration of the reactions and dilution of the medium; the secondary change is largely influenced by temperature and is attended with the complex formation.
