  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.

  The Cr-II complexes CpCr[DppNC(Me)CHC(Me)NC6H4Y] (1; Dpp = 2,6-(Me2CH)(2)C6H3) were used to prepare the corresponding Cr-III iodo (2) and methyl (3) mixed-aryl beta-diketiminate compounds with Y = OMe (a), CH3 (b), H (c), CF3 (d). Oxidation of the Cr-II precursors with iodine gave CpCr[DppNC(Me)CHC(Me)NC6H4Y](I) (2a-d). The Cr-III methyl compounds 3a-d were prepared by reaction of the Cr-II complexes with iodomethane followed by MeMgI. The Cr-III chloride complexes 4a-d were synthesized by salt metathesis of isolated CpCrCl2(THF) with the appropriate deprotonated mixed-aryl beta-diketiminate. The structures of the paramagnetic complexes 1b,c, 2a,b, 3a-d, and 4a-d were determined by single-crystal X-ray diffraction. The rate constants for the single-electron oxidative addition of iodomethane with 1a-d were determined by monitoring the reaction by UV-vis spectroscopy. The rate constants correlated well with the electronic parameters of the Y substituents (rho = -0.36). The rate constants for 1a-d were an order of magnitude greater than those previously obtained for the same reaction with CpCr[(DppNCMe)(2)CH] and related ortho-disubstituted symmetric beta-diketiminate complexes.
