  Reactions of the monomeric β-diketiminate zinc complex MesNacNacZnMe (MesNacNac = [2,6-(2,4,6-Me3–C6H2)-N(Me)C)]2CH}) with ROH (R = Me, Et, iPr) yielded the corresponding zinc alkoxides [MesNacNacZnOR]2 (R = Me 1, Et 2, iPr 3). In addition, the reaction of MesNacNacZnCl with various reducing agents such as potassium graphite, potassium, or sodium gave the ZnII complex [MesNacNac]2Zn 4. Compounds 1–4were

  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.
