    摘要:
    The dimetallic complex, (CO)(5)W(mu-PPh(2)CH(2)PPh(2))W(CO)(5), is synthesized from either a 2:1 mixture of (CO)(5)W(NCMe) and (CO)(5)W(eta(1)-PPh(2)CH(2)PPh(2)) or a 3:1 mixture of (CO)(5)W(NCMe) and PPh(2)CH(2)PPh(2) in toluene at 60 degrees C. The coupling constants, (2)J(PP') = 22.9 Hz, (1)J(WP) = 246.9 Hz and (3)J(WP') = 4.5 Hz are consistent with those reported in the literature for similar complexes. The complex (CO)(5)W(eta(1)-PPh(2)CH(2)PPh(2)) is stable with respect to chelation at room temperature.

    however, this reaction requires an inert atmosphere. While W(CO)6 reacts rapidly with amines to give cis diamine adducts in high yields, direct reactions with phosphines are not so clean. Bis(phosphine) complexes are, however, cleanly formed when a small amount of piperidine is added to the reaction mixture, presumably via the bis(piperidine) complex cis-[W(CO)4(pip)2].

  • Catalysed and uncatalysed substitution reactions of [W(CO)5(NCR)] (R = Me, Et)

    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(CH2)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。
