  Reactivity of bimetallic dibridged complexes Cp2Ta(H)(μ-H)(μ-PMe2)M′(CO)4 (M′ = Cr, Mo, W) toward two-electron donor ligands L (L = PR3, Me2P(CH2)nPMe2). Synthesis of linear trinuclear chain complexes Cp2Ta(H)2(μ-PMe2)M′(CO)4(Me2P(CH2)2PMe2)Cr(CO)5 (M′ = Mo, W)

  摘要：

  The reaction of the heterobimetallic phosphido-and hydride-bridged complexes Cp2TaH(mu-H)(mu-PMe2)M'(CO)(4) (M' = Cr, Mo, W) (1-3) with phosphines (L = PPh2Me, PMe2Ph) or diphosphines (L = dmpm, dmpe) leads to Cp2Ta(H)(2)(mu-PMe2)M'(CO)(4)(L) (1a, 1b, c, d-3b, c, d) with L regiospecifically coordinated to M'. Except for L = PPh,Me, the reaction is stereospecific, since a cis arrangement (with respect to the PMe2 bridge) on the M' site is obtained. The new compounds Cp2Ta(H)(2)(mu-PMe2)M' (CO)(4)(Me2P(CH2)(2)PMe2) (M' = Mo, W) are able to bind [Cr(CO)(5)] fragments affording the linear trinuclear chain compounds Cp2Ta(H)(2)(mu-PMe2)M'(CO)(4)(Me2P(CH2)(2)PMe2) (Cr(CO)(5)) (4, 5). All new complexes have been fully characterized by NMR and IR spectroscopy, and by their elemental analyses. (C) 1997 Elsevier Science Ltd.

  Mono- and di-bridged heterobimetallic systems from group 5 hydride phosphido and hydride phosphino metalloligands. Crystal structure of Cp2Ta(H)( μ-H)( μ-PMe2)Cr(CO)4

  摘要：

  The trihydrides Cp2MH3 (M=Nb, Ta) react with chlorophosphines PR2Cl (R=Me, Ph) affording phosphonium salts [Cp2MH2(PR2H)](+), Cl- (2 (a, b) 2' (a, b)). Depending on the metal (Nb or Ta) and on the nature of the phosphine substituent (Me or Ph), deprotonation of these salts leads to hydride phosphino Cp2MH(PR2H) (3 (a, b) 3'a) or hydride phosphido Cp2TaH2(PPh2) (4'b) metalloligands. These two kinds of complexes are able to bind [M'(CO)(5)] or [M'(CO)(4)] (M' = Cr, Mo, W) organometallic fragments to give mono-or di-bridged heterobimetallic systems. The crystallographic analysis of Cp2Ta(H)(mu-H)(mu-PMe2)Cr(CO)(4) (7'aCr) is reported and discussed. (C) 1997 Elsevier Science S.A.
