  Exceptional substitutional lability of the ‘raft’ cluster Os6(CO)20NCMe

  摘要：

  The kinetics of reactions of the planar 'raft' cluster Os-6(CO)(20)(NCMe) with a wide variety of P-donor ligands, L, in toluene have been studied. Replacement of NCMe by L proceeds via initial, very rapid and reversible formation of the adducts Os-6(CO)(20)(NCMe)L in a pre-equilibrium step which is followed by relatively slow disssociation of the NCMe ligand. The equilibrium and rate constants vary systematically with the electronic and steric natures of the ligands, L, in a way that suggests that bond making by the P-donors in the adducts is comparable with the increase of bond making during the dissociation of NCMe, and that the bonding in the adducts is therefore quite weak. The susceptibility of Os-6(CO)(20)(NCMe) to nucleophilic attack by the P-donors is at least 10(5) times greater than that of Os-3(CO)(11)(NCMe) while the dissociative lability of the NCMe is less by at least a factor of 100.

  The hexa-osmium clusters, [Os6(CO)18] and [Os6(CO)21], have been found to react with P(OMe)3 to yield the blue-green planar cluster complexes [Os6(CO)21-n P(OMe)3}n] (n = 1–6). The same substituted derivatives have been prepared by a range of other synthetic procedures. These include treatment of [Os6(CO)18(MeCN)n] (n = 1–3) (prepared by the direct reaction of [Os6(CO)18] with MeCN) with the phosphite

  已经发现六cluster簇[Os 6（CO）18 ]和[Os 6（CO）21 ]与P（OMe）3反应生成蓝绿色平面簇复合物[Os 6（CO）21- n P（OMe）3 } n ]（n = 1-6）。相同的取代衍生物已经通过一系列其他合成方法制备。这些包括[Os 6（CO）18（MeCN）n ]（n = 1-3）的处理（通过[Os 6（CO）18的直接反应制备用亚磷酸酯用MeCN]处理[Os 6（CO）21- n（MeCN）n ]（n = 1，2）[通过[Os 6（CO）21 ]与MeCN直接反应制备，或通过亚磷酸酯催化[Os 3（CO）12- n（MeCN）n ]（n = 1，2 ）的催化二聚，或通过亚磷酸酯的羰基化。通过IR和NMR光谱相结合，以及在某些情况下通过单晶X射线衍射研究，对新的取代衍生物进行了表征。所有十五种可能的衍生物均已表征。
