Abstract
Anilines undergo oxidative carbonylation in the presence of methanol, carbon monoxide, oxygen and base. Elemental sulfur or low molecular su lfur derivatives (CS2, COS) were studied as new and efficient catalyst s at temperatures 393-423 K and pressure 8-13 MPa. Methyl-N-phenyl car bamate as product is formed through N,N'-diphenylurea as an intermedia te. Studies of the methanolysis of this intermediate have shown, that this reaction step is catalysed by bases and does not need CO, oxygen or sulfur catalyst.
