  后期过渡金属络合物在乳液聚合中由于水可能引起的副反应。1.水络合和水解的增长链。

  摘要：

  在过去的几年中，水性乳液中过渡金属催化的乙烯聚合越来越成功。然而，水通过（a）与乙烯竞争金属上的结合位点和（b）水解生长链而对聚合过程产生不利影响。本文通过密度泛函理论研究了具有不同取代基模式的Ni和Pd的中性水杨醛亚氨基和阳离子二亚胺配合物，以确定它们对水络合和生长链水解的倾向。还已经对基于Ni（II）的Grubbs催化剂的质子分解进行了NMR实验研究。发现通常，对于Ni和Pd催化剂，（a）乙烯配位优于水配位，并且（b）金属烷基键的水解与乙烯插入竞争。

  The neutral kappa N-2,O-salicylaldiminato Ni(II) complexes [kappa N-2,O-(2,6-(3',5'-R2C6H3)(2)C6H3-N=C(H)-(3,5-I-2-2-O-C6H2)}]NiCH3(pyridine)] (1a-pyr, R = Me; 1b-pyr, R = Et; 1c-pyr, R = iPr) convert ethylene to hyperbranched low-molecular-weight oligomers (M-n ca. 1000 g mol(-1)) with high productivities. While all three catalysts are capable of generating hyperbranched structures, branching densities decrease significantly with the nature of the remote substituent along Me > Et > iPr and oligomer molecular weights increase. Consequently, only 1a-pyr forms hyperbranched structures over a wide range of reaction conditions (ethylene pressure 5-30 atm and 20-70 degrees C). An in situ catalyst system achieves similar activities and identical highly branched oligomer microstructures, eliminating the bottleneck given by the preparation and isolation of Ni Me catalyst precursor species. Selective introduction of one primary carboxylic acid ester functional group per highly branched oligoethylene molecule was achieved by isomerizing ethoxycarbonylation and alternatively cross metathesis with ethyl acrylate followed by hydrogenation. The latter approach results in complete functionalization and no essential loss of branched oligomer material and molecular weight, as the reacting double bonds are close to a chain end. Reduction yielded a monoalcohol-functionalized oligomer. Introduction of one reactive epoxide group per branched oligomer occurs completely and selectively under mild conditions. All reaction steps involved in oligomerization and monofunctionalization are efficient and readily scalable.
