  摘要：

  The kinetics of the ring-closure reactions of Mo(CO)5L, produced during the laser flash photolysis of Mo(CO)6 and L where L = 2,2'-bipyridine (bpy), 4,4'-dimethyl-2, 2'-bipyridine (dmpby) and 4,4'-diphenyl-2,2'-bipyridine (dpbpy) were studied as a function of temperature and pressure. The values of the activation parameters DELTA-S(double dagger) and DELTA-V(double dagger) are small and negative for L = bpy and dmbpy supporting an associative interchange mechanism (I(a)) for CO extrusion. For L = dpbpy, DELTA-V(double dagger) is small and positive in line with a dissociative interchange mechanism (I(d)). The results demonstrate a changeover in mechanism from I(a) to I(d) with increasing steric hindrance on the bidentate ligand L.

  of seven-coordinate tungsten(II) salts [W(CNR)5(NN)](PF6)2 (R = CHMe2, CMe3, C6H11, or CH2Ph; NN = bipy, Me2bipy, or phen) have been prepared in high yield (75%). The synthetic procedure involves the oxidation of the metal carbonyl derivative W(CO)4(NN) with iodobenzene dichloride, followed by displacement of carbon monoxide and chloride ligands from the intermediate W(CO)3(NN)Cl2 by alkyl isocyanide

  一系列七配位的钨（II）盐[W（CNR）5（NN）]（PF 6）2（R = CHMe 2，CMe 3，C 6 H 11或CH 2 Ph; N = N =高产率（75％）制备了Bipy，Me 2 Bipy或phen）。合成过程涉及用二氯化碘苯氧化羰基金属衍生物W（CO）4（NN），然后用三氯甲烷从中间体W（CO）3（NN）Cl 2取代一氧化碳和氯化物配体。烷基异氰。这些反应对于将Mo（CO）4（NN）转化为[Mo（CNR）5（NN）]（PF 6）2。的脱烷基化[W（CNCMe 3）5（NN）]（PF 6）2，得到[W（CNCMe 3）4（NN）} 2（μ-CN）]（PF 6）3发生在回流的乙醇中。[W（CNCMe 3）7 ]（PF 6）2与NN在回流的1-丙醇中的直接反应导致脱烷基化产物[W（CNCMe 3）6（CN）] PF 6，但没有证据代替Me 3NN通过这种途径进行CNC配体。
