Previously unknown substituted benzenesulfonyl isothiocyanates were synthesized via pyrolysis of N-substituted Benzenesulfonyl dithio-carbamic esters and their properties studied. Their quantitative reactivities with lower alkyl amines to yield the corresponding N-substituted benzenesulfonyl-N -alkyl thioureas present the bases for the new analytical method for isothiocyanates. This method has been success fully employed for the study of the pyrolysis conditions. Upon mixing with alcohols, the isothiocyanates are similarly converted to N-substituted benzenesul fonyl thiocarbamic esters in an almost quantitative manner. The N-substituted benzenesulfonyl isothiocyanates tend to form polymers, (RC6H4SO2NCS)n, which dissociate into the monomeric components in chloroform. Though their molecular weights could not be determined, their reactivities with lower alkyl amines and alcohols similar to that of the monomers sugge st that the polymers are of n=2-3 and highly dissociative.
