摘要: Urethanes are prepared by oxidative carbonylation of at least one amino compound in the presence of carbon monoxide, oxygen and organic, at least one hydroxyl-group-carrying compound. The carbonylation is carried out in the absence of halogen-containing promoters. The carbonylation is also carried out in the presence of a metal complex catalyst which contains neutral bidentate N-chelate ligands of the (N˜N) type, two monoanionic N,O-chelate ligands of the general type (N˜O)− or tetradentate dianionic chelate ligands (O˜N˜N˜O)2−.

摘要: 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.
