The preparations and properties of a number of substituted thionocarbamates are described.
A number of benzyloxyamines were prepared for conversion into urea and thiourea derivatives. The benzyloxyamine hydrochlorides on treatment with phosgene gave a mixture of the corresponding benzyl 4-(benzyloxy)-allophanate and benzyloxycarbamyl chloride. Triethylamine converted the benzyloxycarbamyl chlorides into the corresponding 1,3,5-tri-(benzyloxy)-isocyanuric acids. The reactions of the allophanates with amines and sodium hydroxide are described.
