  Synthesis of Rh(I) and Ir(I) complexes with chiral C2-multitopic ligands

  摘要：

  Four multitopic ligands, N,N'-bis[(S)-prolyl)phenylenediamine, N,N'-bis{[(S)-pyrrolidin-2-yl]methyl}phenylenediamine, N,N'-bis[(S)-N-benzylprolyl]phenylenediamine, N,N'-bis{[(S)-N-benzyl-pyrrolidin-2-yl]methyl}phenylenediamine, were synthesised and their co-ordination properties with Rh(I) and Ir(I) studied. The complexes were prepared by the reaction of [MC](cod)](2) with AgPF6 and further treatment with the ligand. All ligands form one to one [ML] species with the above metal ions. The structures of these complexes were elucidated by analytical and spectroscopic data (elemental analysis, mass spectroscopy, IR, H-1- and C-13-NMR). Complexes show excellent activities and enantioselectivities up to 30% for the hydrogenation of prochiral olefins under mild reaction conditions. (C) 2001 Elsevier Science B.V. All rights reserved.

  Eight mononuclear complexes with multitopic C-2-symmetry ligands, [Cu(L)]ClO4, [Mn(L)Cl(H2O)]PF6, (L = N,N'-bis[(S)-prolyl]phenylenediamine (1), N,N'-bis[(S)-N-benzylprolyl]phenylenediamine (2), N,N'-bis[(S)-pyrrolidin-2-yl]methyl}phenylenediamine (3), N,N'-bis-[(S)-N-benzyl-pyrrolidin-2-yl]methyl}phenylenediamine (4)) have been prepared and characterised by analytical (elemental analysis, and mass spectroscopy) and FT IR, NMR and electronic spectroscopies. The data show that the ligands are neutral and coordinate to the metal in a tetradentate manner. The N,N'-bis[(S)-prolyl]phenylenediamine ligand also appears as an anionic species, (LH-2), and the single crystal structure determination of the respective complex, [Cu(1)]H2O, is reported. This new family of Cu-complexes catalyse the cyclopropanation of styrene with ethyl and t-butyl diazoacetate to afford cis/trans 2-phenylcyclopropan-1-carboxylates with good yields and selectivity against dimerisation and low ee ( < 10%). On the other hand, the manganese and copper complexes also catalyse the oxidation of organic sulfides to sulfoxides with high selectivity, and moderate to low en antioselectivity. If an excess of oxidant were used the reaction yields sulfone as only product with excellent yield. (C) 2002 Elsevier Science B.V. All rights reserved.
