  Hydroxyalkyl Complexes and Hemiaminal Formation in the Reaction of o-Diphenylphosphinobenzaldehyde with Rhodium(I) Dihydrazone Complexes

  摘要：

  The diimino complex Rh(COD)(bdh)Cl (bdh: H2NN=C(Me)C(Me)=NNH2) reacts with o-diphenylphosphino(benzaldehyde) (PCHO) in the presence of PPh3 to give acylhydrido [Rh(H)(PCO)(PPh3)(bdh)](+) species. When using Rh/PCHO 1:2 stoichiometric ratios, oxidative addition of one PCHO and P-coordination of another PCHO occurs. The aldehyde group then undergoes two competitive reactions: (i) addition of one free amino group to give a stable hemiaminal and a complex [Rh(H)(PCO)(Pbdh)](+) that contains a new PNN ligand coordinated via the imino nitrogens and the phosphorus atom or (ii) insertion into Rh-H to give the hydroxyalkyl complex [Rh(PCO)(PCHOH)(bdh)](+) The complexes have been fully characterized, and X-ray diffraction structures of both of them are reported. Some intermediates in the competitive reactions have been spectroscopically characterized, and the transformation of the hemiaminal group into imine to give a PaNN ligand in the complex [Rh(H)(PCO)(Pabdh)](+) has also been studied.
