Abstract: A new three-component catalytic system (S and its compounds +CH₃COONa+V₂O₅) can be used for reductive carbonylation of PhNO₂ with CO and CH3OH which gives methyl N-phenylcarbamate and aniline. The initial carbon monooxide pressure is equal to 14 MPa at 298 K and the reaction takes place at 360-470 K. Moreover, the influence of components (S or CS₂ and V₂O₅) of the catalytic system as well as of water addition on initial reaction rate and selectivity of the reaction has been examined. The reaction mechanism is discussed. It has been proved that the hydrogen from water molecule is taking part only indirectly in the reaction with PhNO₂ to give PhNH₂.
