The new catalytic system PdCl2/Fe/I-2/Pyridine, active in nitrobenzene carbonylation to ethyl phenylcarbamate (EPC) is presented. For the catalyst composition determined by the following ratio: 0.17/10/1.4/12.1 of its components respectively, at 180 degrees C; under initial CO pressure = 4 MPa, after 2 h, a nitrobenzene conversion reached 99.6%, the percentages of the products obtained were: 83.4% EPC and 14% aniline (NB/Pd = 540). Influence of initial CO pressure, reaction temperature, reaction time and the catalyst composition on the reaction products, were established.
