Abstract

The invention comprises a process of preparing N-carbamoyloxyphenyl carbamates of the formula in which R 4 and R 5 denote hydrogen atoms or aliphatic hydrocarbon groups and R 1 , R 2 and R 3 denote aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic groups, any of which may carry one or more specified substituents, including halogen atoms and alkyl, halogenalkyl and alkoxy groups alternatively, R 1 and R 2 may denote hydrogen atoms or, together with the adjacent nitrogen atom, may denote a heterocyclic group that may contain at least one further nitrogen atom or an oxygen atom. The process of the invention consists in reacting a compound of the formula in which X denotes a hydrogen atom, a monovalent metal or an ammonium, N-alkylammonium, N,N-dialkylammonium or N,N,N- trialkyl-anunonium group, with phosgene in the presence of an amine of the formula R 6 N(R 1 )R 2 , in which R 6 denotes a hydrogen atom or an aliphatic hydrocarbon group. In a modification of the process, the reaction of phosgene with the N-hydroxyphenyl urethane, which yields a chloroformic ester, may precede the reaction with the amine R 6 N(R 1 )R 2 . The reaction may be effected at 0-100 C., optionally in the presence of a solvent and an acid-binding agent, which may be an excess of the amine. A number of phenyl urethanes and amines for use as starting materials are specified, and numerous products obtainable by the process of the invention are listed.
