    Phosphine Boranes in Coordination Chemistry:  An Efficient Method for the Synthesis of Chiral and Achiral Organophosphorus Pentacarbonyltungsten Complexes
    摘要:
    Organophosphorus boranes 1-6 and amine pentacarbonyltungsten complexes 14-20 react under mild conditions, to afford by Ligand exchange the corresponding W(CO)(5)(PR3) 21-26 derivatives in 63-92% yields. The use of piperazine 13 as a diamine tungsten substituent permits a tandem reaction which removes the borane group and leads to the formation of the corresponding organophosphorus tungsten complex. The stereochemistry of the formation of pentacarbonyltungsten complexes from tertiary chiral organophosphorus borane compounds proceeds with a high stereoselectivity and retention of configuration at the chiral P center.

    Abstract The reaction between [W(CO)5(NCR)] (R = Me, Et) and tBuNC in the presence of PdO yielded both [W(CO)4(CNBut)2] and [W(CO)4(NCR)(CNBut)] and revealed that both RCN and CO are catalytically replaced by tBuNC. Reaction of a 2:1 mixture of [W(CO)5(NCMe)] and PPh2(CH2)nPPh2 (P-P; n = 2, 5) in toluene at 55 °C gave a product mixture consisting of the bridged complex [W(CO)5(P-P)W(CO)5] (dominant product)
    摘要[W(CO)5(NCR)](R = Me,Et)与tBuNC在PdO存在下的反应产生了[W(CO)4(CNBut)2]和[W(CO)4(NCR) )(CNBut)],并发现RCN和CO均被tBuNC催化取代。[W(CO)5(NCMe)]与PPh2(CH2)nPPh2(PP; n = 2,5)的2:1混合物在甲苯中于55°C反应,得到由桥联配合物[W]组成的产物混合物(CO)5(PP)W(CO)5](主要产物)和螯合物[W(CO)4(PP)]。出乎意料的是,当与PPh2( )nPPh2(n = 4,5)的反应在CHCl3中进行时,螯合物[W(CO)4(PP)]是主要产物。

    1 H-183W}, 1H-31P}, and 1H-183W, 31P} nuclear magnetic double- and triple-resonance experiments have been used to determine tungsten-183 chemical shifts and other parameters in 35 tungsten(0) complexes with tertiary phosphine, η-cyclopentadienyl, and other ligands.
