  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.

  日期：——

  A series of zinc (II) complexes has been prepared based on a beta-diketiminate inland framework and exhibits the highest rate of polymerization with better stereoselectivity in the formation of polylactic from the rac-lactide with aggregation and narrow polydisperties. Degree of aggregation and their reactivity's depends on the nature of alkoxy groups, the role of metal ion, solvent and their structural properties. The nature of substituent group on beta-diketiminate ligand exerts a significant change a fleeting both the degree of selectivity and the rate of polymerization. The polymerizations are living, as evidenced by the narrow polydisperties and with their linear nature and average molecular weight.
