  Synthesis and characterization of new RhI complexes bearing CO, PPh3 and chelating P,O- or Se,Se-ligands: Application to hydroformylation of styrene

  摘要：

  The complexes [Rh(CO)(PPh3){Ph2PNP(O)Ph-2-P,O}] (3), [Rh(CO)(2)(Ph2P(Se)NP(Se)Ph-2-Se,Se')] (5), and [Rh(CO)(PPh3){Ph2P (Se)NP(Se)Ph-2-Se,Se')] (6), were synthesised by stepwise reactions of CO and PPh3 with [Rh(cod){Ph2PNP(O)Ph-2-P,O)1 (2) and [Rh(cod)(Ph2P(Se)NP(Se)Ph-2-Se,Se')] (4), respectively. The complexes 3, 5 and 6 have been studied by IR, as well as H-1 and 3 1 P NMR spectroscopy. The v(CO) bands of complexes 3 and 6 appear at approximately 1960 cm(-1), indicating high electron density at the Rh-1 centre. The structure of complexes 3 and 6 has been determined by X-ray crystallography, and the P-31? NMR chemical shifts have been resolved via low temperature NMR experiments. Both complexes exhibit square planar geometry around the metal centre, with the five-membered ring of complex 3 being almost planar, and the six-membered ring of complex 6 adopting a slightly distorted boat conformation. The C-O bond of the carbonyl ligand is relatively weak in both complexes, due to strong R-back donation from the electron rich Rh-1 centre. The catalytic activity of the complexes 2, 3 and 6 in the hydroformylation of styrene has been investigated. Complexes 2 and 3 showed satisfactory catalytic properties, whereas complex 6 had effectively no catalytic activity. (c) 2007 Elsevier B.V. All rights reserved.

  Preparation and characterisation of [Pt{N(SePPh₂)₂-Se,Se′}(PR₃)₂]Cl (R = alkyl or aryl); crystal structure of [Pd{Ph₂PNP(Se)Ph₂-P,Se}{N(SePPh₂)₂-Se,Se′}]·0.5EtOH·0.3CH₂Cl₂

  摘要：

  Reaction of NH(PPh(2))(2) with selenium gives Ph(2)P(Se)NHP(Se)Ph(2) which may be deprotonated with KOBu(t) to give K[Ph(2)P(Se)NP(Se)Ph(2)]. This can be treated with appropriate Group VIII metal complexes to give [Rh{N(SePPh(2))(2)}(cod)] (cod = cycloocta-1,5-diene), a series of complexes of formula [Pt(N(SePPh(2))(2)-Se,Se')(PR(3))(2)]Cl (PR(3) = PMe(3), PMe(2)Ph, PEt(3), PPh(3), 1/2NH(PPh(2))(2) or 1/2Ph(2)PCH(2)CH(2)PPh(2)) and [MCl{N(SePPh(2))(2)-Se,Se'}(PMe(2)Ph)] (M = Pt or Pd). The new compounds have been characterised by P-31 and Pt-195 NMR and IR spectroscopy, FAB(+) mass spectrometry and microanalyses. Furthermore, a small quantity of a mixed-ligand complex [Pd{Ph(2)PNP(Se)Ph(2)-P,Se}{N(SePPh(2))(2)-Se,Se'}]. 0.5EtOH . 0.3CH(2)Cl(2) has been characterised by X-ray crystallography and P-31 NMR spectroscopy. Its structure reveals an approximately planar five-membered PdSeP2N ring and a puckered six-membered PdSe2P2N ring. in the crystal the molecules pack with channels which contain the disordered CH2Cl2 molecules running down the a direction.
