1-Chloroalkyl isocyanates react with thiourethanes to gives N-acylation products, namely, N-(N-alkylidenaminocarbonyl)thiourethanes, which exist in solution in tautomeric equilibrium with S-(1-isocyanatoalkyl)isothiourethanes.These tautomeric transformation occur in the C=N-C azaallylic system involving a new anionotropic migrant, namely, the thiocarbamyl group.The reactions of these tautomeric compounds with water, alcohols, phenol, and primary amines proceed with the participation of the azomethine form, while the reactions with secondary amines involve the isocyanate form.

The conditions for the isomerization of N-carbodiimides to N-alkylidene-N'-acylureas were investigated.In the reaction of N-carbodiimides with alcohols, phenols, thiophenols, and imines fragmentation of the carbodiimides occurs with the formation of 1-alkoxy-, 1-aryloxy-, 1-arylthio-, and 1-alkylideneaminoalkyl isocyanates and amides.The products from the reaction with water and with tert-butylamine are the amide, ketone, and N-alkylimine.
