  名称：

  A convenient route to vinylsiloxane-tertiary phosphine-nickel(0) complexes; the molecular structure of [(Ni{P(C6H4Me-4)3})2{μ-(L′′L′′)2}] {(L′′L′′)2=[CH2CH(Me)Si(μ-O)]4}

  摘要：

  A simple one pot synthesis in Et2O at ambient temperature, from the readily available starting materials [Ni(cod)(2)], PR3 and LL or (L " L ")(2), provides an essentially quantitative route to the known vinylsiloxanenickel(0) complexes [Ni(LL)PR3] and the new binuclear analogues [{Ni(PR3)}(2){mu-(L " L ")(2)}] (5) {LL = [CH2CH(Me)(2)Si](2)O, (L " L ")(2), = [CH2CH(Me)Si(mu-O)](4) and R =Ph, C6H4Me-4 or C6H11-c}. The X-ray crystal structure of 5b (R = C6H4Me-4) shows it to be a centrosymmetric binuclear complex containing (L " L ")(2) as a chair-shaped bridging ligand. It is bound to each Ni(PR,) moiety by a pair of mu(2)-vinyl groups (having M and M' as centroids) and each NiMSiOSi'M' metallacycle is;also of chair conformation. (C) 2000 Elsevier Science S.A.
