Abstract

PURPOSE: To obtain the titled compound useful as an intermediate for preparing an aromatic isocyanate advantageously in one stage, by reacting an aromatic compound with a cerbamic ester in the presence of a catalyst.
CONSTITUTION: An aromatic compound, e.g. benzene, toluene, pyridine or diphenylmethane, is reacted with a carbamic ester of the formula H2NCOOR (R is alkyl or aryl), e.g. methyl carbamate or a carbamic ester of carbamic acid with an alcohol, in the presence of a metal of Group VIII in the periodic table, e.g. a metal selected from Ru, Rh, Pd or Pt, or a compound thereof, as a catalyst at 0W300°C for several secondsWseveral hours to give the aimed compound. The reaction may be carried out in the presence of a solvent, e.g. a hydrocarbon or halogenated hydrocarbon, or an additive, e.g. oxygen, air, S orI.
