    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.

    摘要: The present invention describes homoleptic, ortho-metalated, chelate-stabilized benzylamine complexes of the rare-earth metals. The rare-earth metals are selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu. In the complexes according to the present invention, at least one benzylic proton of the benzylamine ligand is replaced by an alkyl or aryl group. Such complexes are preferred in which both benzylic protons of the benzylamine ligand are replaced by an alkyl- or aryl group. The complexes according to the present invention are produced by reaction of chelate-stabilized rare-earth metal halides with ortho-lithiated aryl ligands at room temperature under inert gas atmosphere. The complexes according to the present invention are thermally stable and suitable for being used as catalysts for the hydroamination of olefins.
