  Rh and Ir complexes containing multidentate, C2-symmetry ligands. Structural and catalytic properties in asymmetric hydrogenation

  摘要：

  A comparative investigation of the interaction of Rh(I) and Ir(I) with a series of mixed-donor multidentate, C-2-symmetry ligands has been carried out. The complexes have been prepared by the reaction of [MCl(cod)](2) (cod = 1,5-cyclooctadiene) with AgPF6 and further treatment with the ligand. All ligands form 1:1 (metal:ligand) species with the above metal ions although, in a few instances, species of type [M2L2](2+) were also detected. The structures of these complexes were elucidated by analytical and spectroscopic data (elemental analysis, mass spectroscopy, IR, H-1- and C-13-NMR). Complexes were tested in the asymmetric hydrogenation of prochiral olefins, providing enantioselectivities up to 36%. (C) 2000 Elsevier Science S.A. All rights reserved.

  Abstract A novel tridentate chiral imidazolium hexafluorophosphate, a precursor for N-heterocyclic carbene (NHC) ligand, was synthesized from (S)-proline in five steps in 24% overall yield. The compound was characterized by NMR and elemental analysis. Its molecular structure was determined by X-ray diffraction analysis. This chiral compound has two stereogenic centers which are within two chelating

• Homogeneous and encapsulated within the cavities of zeolite Y chiral manganese and copper complexes with C2-multidentate ligands as catalysts for the selective oxidation of sulphides to sulfoxides or sulfones

  A series of manganese and copper complexes with tetradentate C-2-symmetry ligands, [Mn(C-2-ligand)Cl(H2O)]PF6 and [Cu(C-2-ligand)]ClO4, have been synthesised and characterised as homogeneous and encapsulated into the supercages of a large pore sized USY zeolite. These Mn and Cu complexes are excellent catalysts for the selective oxidation of organic sulphides to sulfoxides or sulfones with high selectivity, and moderate to low enantioselectivity. The chelation of zeolite-exchanged Mn2+ by C-N-containing ligands gives rise to a whole class of heterogeneous liquid phase oxidation, which exhibits similar catalytic performances than the homogeneous ones. Moreover, those heterogenised catalysts can be recycled in successive runs, by a simple filtration, without a significant loss of activity and selectivity. (C) 2002 Elsevier Science B.V.

  The reaction of [Cu(CH3CN)(4)]X (X = ClO4, PF6) with multidentate ligands N,N'-bis[(S)-prolyl]ethylenediamine (1), N,N'-bis[(S)-N-benzylprolyl]ethylenediamine (2), N,N'-bis [(S)-pyrrolidin-2-yl]methyl}ethylenediamine (3), N,N'-bis-[(S)-N-benzylpyrrolidin-2-yl]methyl}ethylenediamine (4) gives copper complexes which were characterised by analytical (elemental analysis, and mass spectroscopy) and FT IR, NMR and electronic spectroscopies. The [Cu(N,N'-bis[(S)-prolyl]ethylenediamine)]-ClO4}(2).(MeCN)(2) complex was characterised by X-ray crystallography. This new family of Cu-complexes catalyse the cyclopropanation of styrene with ethyl and t-butyl diazoacetate to yield cis/trans 2-phenylcyclopropan-1-carboxylates in good yields and selectivity against dimerisation and low ee (<10%).
