    摘要:
    苯烷基膦Ph 2 PR,PhPR 2(R = Bu,iPr)与Na / NH 3的还原裂解是非选择性的:苯基和烷基都可以裂解,并且可能发生桦木还原。Ph 2 tBuP的反应产生了高产率的二苯基磷化物。伯烷基的ω位置的极性基团(CO 2 Na,SO 3,Na)可能导致选择性增加;桦木还原得到抑制,并获得官能化的仲磷化物。

    摘要:
    通过Rapid Inject NMR和竞争实验观察到,与酯和酮相比,烷基锂试剂和酰胺之间的反应速率异常高。用4-氟苯基锂(ArLi,单体和二聚体在THF中的混合物)和苯甲酸酯进行的光谱研究确定了两个反应性中间体,即四面体中间体的均二聚体(在100°C以下稳定),以及与ArLi混合的二聚体。直接形成二聚体表明ArLi二聚体可能是反应性聚集体,而不是通常更具反应性的单体。相反,用酮进行的RINMR实验表明ArLi单体是反应性物质。

  • Zirconium and hafnium complexes based on 2-aryl-8-arylaminoquinoline ligands: synthesis, molecular structure, and catalytic performance in ethylene copolymerization

    A general and efficient approach toward new zirconium and hafnium complexes based on 2-aryl-8-arylaminoquinoline ligands was developed. These precursors, when activated with MAO/borate cocatalyst and supported on silica, result in active olefin polymerization catalysts. The ethylene copolymers produced under industrially relevant conditions show very high molecular weights and unique microstructures defined by the multisite nature of the catalyst. A site-diversification mechanism is proposed to explain the presence of at least five individual sites, as deduced from 3D-TREF analysis of ethylene–butene copolymers.
