Abstract
N-(p-Substituted benzenesulf onyl)-isocyanodichlorides were prepared from the corresponding benzenesulf onyl-isothiocyanates and chlorine in a good yield. Similar reactions, however, did not take place between highly dissociative low polymers of isothiocyanate and chlorine.Following reactions of the isocyanodichlorides were also investigated. (1) Form-ation of carbamic esters and imidocarbonic diesters by treatment with alcohols and sodium alcoholates; (2) formation of chloroformamidines and guanidines by treat-ment with amines and amides; and (3) formation of tritosylguanidine by treatment with tosylamide.
