    Asymmetric epoxidation catalyzed by Cr(III)-binaphthyl Schiff base complexes
    摘要:
    A series of chromic complexes with binaphthyl Schiff base as ligands are synthesized. Their catalytic abilities in asymmetric epoxidation and the effects of reaction conditions such as temperature, solvent and additive have also been studied. leading to the highest ee of 65% for 4-chlorostyrene; the reaction seems to involve a Cr(V)-oxo active species, (c) 2005 Elsevier B.V.

    配对增强的区域选择性:由外消旋甲基乙交酯合成交替聚乳酸-乙醇酸共聚物
    摘要:
    聚乳酸乙醇酸(PLGA)在体内用于各种生物医学应用。由于其生物降解性和生物相容性,PLGA 特别适合肠胃外给药的受控药物输送。此前,我们建立了从对映体纯起始材料合成全同立构、交替 PLGA 的方法。在这里,为了填补当前领域的空白,我们开发了从外消旋甲基乙交酯(rac-MeG )合成间二富集的交替PLGA的方法。交替PLGA的合成是通过外消旋-MeG与优化的外消旋铝催化剂的高度区域选择性开环聚合来完成的。进行机理研究以阐明配对增强催化剂的区域控制和立体控制。聚合物序列保真度已通过核磁共振研究确定,证实了主链立体构型内共聚单体序列的高度交替和中等的间同立构规整度。所得间二富集材料是无定形的,这将有利于药物络合行为。

    synthesized and investigated as catalysts in ring-opening polymerization (ROP) of cyclic esters such as rac-lactide (rac-LA) and ε-caprolactone (ε-CL) and in the copolymerization (ROCOP) of phthalic anhydride (PA) with cyclohexene oxide (CHO) and limonene oxide (LO). The polymerizations of cyclic esters were living, producing polymers with narrow molar mass distributions. Kinetic studies showed that the
    两种双核铝络合物轴承二桥接席夫碱已被合成和研究作为在环酯的开环聚合(ROP)催化剂,如外消旋-丙交酯(外消旋-LA)和ε-己内酯(ε-CL),以及邻苯二甲酸酐(PA)与环己烯氧化物(CHO)和柠檬烯氧化物(LO)的共聚(ROCOP)。环状酯的聚合反应活跃,产生具有窄摩尔质量分布的聚合物。动力学研究表明,聚合反应相对于单体而言是一阶的。尽管配合物的刚性骨架增强了与丙交酯相比较少阻碍的己内酯的反应性,但调用了位于近端位置的两个属中心之间的协同作用以合理化对两种单体的高活性。在邻苯二甲酸酐与环己烯环氧化物和与生物衍生的柠檬烯的共聚中也获得了良好的活性。
  • Synthesis and Characterization of New Chiral Schiff Base Complexes with Diiminobinaphthyl or Diiminocyclohexyl Moieties as Potential Enantioselective Epoxidation Catalysts

    New chiral Schiff base complexes have been obtained by condensation of 2,2'-diamino-1,1'-binaphthalene or 1,2-diaminocyclohexane and various salicylaldehydes and by subsequent metalation with manganese, iron, cobalt, nickel, copper, or zinc. The complete (1)H and (13)C NMR characterization of the ligands is reported, as are the X-ray crystal structures of (1R,2R)-(-)-N,N'-bis[3-(N,N-dimethylamino)

  • Polymerization of ethylene and propene promoted by binaphthyl-bridged Schiff base complexes of titanium
    作者:Maria Strianese、Marina Lamberti、Mina Mazzeo、Consiglia Tedesco、Claudio Pellecchia
    DOI:10.1016/j.molcata.2006.05.046
    日期:2006.10
    Three new binaphthyl-bridged Schiff base complexes featuring different phenolate substituents (meta-Me, orthopara-di-Cl, orthopara-di-Br) were synthesized. H-1 and C-13 NMR analyses indicated that the cis-beta isomers are preferentially formed in any case. These complexes were tested as precatalysts for ethylene and propene polymerization comparing their behaviour to that of related titanium and zirconium complexes previously reported.The beneficial effect on polymerization activity of halogen atoms in the ortho, para positions of the phenolate rings was also demonstrated.
