Process for producing aryl carbamates

PCT No. PCT/JP98/00592 Sec. 371 Date Oct. 13, 1998 Sec. 102(e) Date Oct. 13, 1998 PCT Filed Feb. 13, 1998 PCT Pub. No. WO98/35936 PCT Pub. Date Aug. 20, 1998A process for producing an aryl carbamate of a high purity at a high yield by reacting a diaryl carbonate with an amine compound having one or more hydrogen atoms bonded to the N position in the presence of carboxylic acid(s) of the following general formulae (I): R1-COOH and/or (II): R2-COOH (wherein R1 represents an alkyl or cycloalkyl group having an alpha -positioned carbon atom bonded to only one hydrogen atom, an alkyl group having an alpha -positioned carbon atom bonded to no hydrogen atom, or an aryl or heterocyclic group, and R2 represents an alkyl group having an alpha -positioned carbon atom bonded to two or more hydrogen atoms).
