  摘要：

  描述了不对称取代的β-二酮亚胺，2-（2-甲氧基苯基亚氨基）-4-（2,6-二异丙基苯基氨基）戊-2-烯（BDI-2）H的合成及其与镁和锌的络合化学被探索。重点放在用于丙交酯开环聚合的醇盐和酰胺衍生物的制备上。将其作为聚合引发剂的行为与N，N'-双（2,6-二异丙基苯基）β-二酮化配体BDI-1所支持的类似化合物进行了比较。（BDI-2）H与Me2Mg反应生成双（螯合物）配合物（BDI-2）2Mg，3。BDI-2负载的镁烷基可以通过增加烷基的大小来制备。因此，（BDI-2）H的锂化得到[（BDI-2）Li] 2，4; 其随后用iPrMgCl处理会产生（BDI-2）MgiPr，5。使用iPr2NH对复合物进行氨解会生成酰胺复合物，（BDI-2）MgNiPr2，6。Zn（NTMS2）2和ZnEt2与（BDI-2）H反应，分别得到（BDI-2）Zn（NTMS2），7和（BDI-2）ZnEt，8。

  Comparative study of lactide polymerization by zinc alkoxide complexes with a β-diketiminato ligand bearing different substituents

  摘要：

  A series of beta-diketiminate zinc complexes has been synthesized and their reactivity for the ring-opening polymerization (ROP) of lactide has been studied. The reaction of beta-diketimines (LH) with diethyl zinc forms the monomeric [LZnEt] complexes which further react with benzyl alcohol (BnOH) in toluene/hexane yielding dinuclear or trinuclear zinc complexes. These complexes have been characterized by single crystal X-ray diffraction, which showed the tri- and tetra-coordinated zinc complexes in which zinc atoms exhibit trigonal and tetrahedral geometry, respectively. All complexes have been tested as initiators for the ring-opening polymerization of lactide: they are all highly active. The rate of polymerization is heavily dependent on the N-aryl substituents with the order: alkyl group similar to alkoxy > halide group > nitro group. The beta-diketiminate zinc complexes allow controlled ring-opening polymerization as shown by the linear relationship between the percentage conversion and the number-average molecular weight. On the basis of literature reports, a mechanism for ROP of lactide has been proposed. (C) 2011 Elsevier B.V. All rights reserved.
