Production of N-aryl Carbamates and N-aryl Isocyanates |
abstract |
The invention relates to a method for producing N-aryl carbamates (urethanes) and N-aryl isocyanates. According to said method, aromatic nitro compounds are subjected to a reductive carbonylation in the presence of carbon dioxide and organic compounds that bear hydroxyl groups and the carbonylation is carried out in the presence of metal complexing catalysts. Anionic N,O-chelate ligands of the general formulae [M(N˜O) − 2 ] and [M(O˜N˜N˜O) 2− ], containing a divalent or trivalent transition metal of groups 5-11 are used for the catalysts. |
