    摘要:
    1,2-双硼酸酯是多功能中间体,可以快速制备简单的烯烃前体。先前关于其选择性单官能化的报告针对的是最容易接近的位置,保留了受阻更多的仲硼酸酯。相比之下,我们发现光氧化还原催化的单脱硼作用会产生初级 β-硼基自由基,这些自由基经历快速的 1,2-硼转移以形成热力学有利的二级自由基,从而允许更多受阻硼酸酯的选择性转化。已被证明具有立体保留性的关键 1,2-硼位移能够获得广泛的官能化硼酸酯,并已应用于高度非对映选择性断裂和跨环环化反应。此外,

  • PROCESS FOR PRODUCING CARBOXY-TERMINATED LACTONE POLYESTER/UNSATURATED MONOMER
    申请人:DAICEL CHEMICAL INDUSTRIES, LTD.
    公开号:EP1632469A1
    公开(公告)日:2006-03-08
    A method produces an unsaturated lactone-derived polyester monomer of Structural Formula (1): wherein each of R1, R2, R3, R4, R5, R6, and R7 represents a substituent selected from hydrogen atom, a substituted or unsubstituted alkyl group having one to ten carbon atoms, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, and a halogen atom; n denotes an integer from 1 to 7; and m denotes an integer from 1 to 100, by reacting a carboxyl-containing radically polymerizable unsaturated monomer with a cyclic lactone using an acidic catalyst at normal pressure in the presence of 1 to 50 parts by weight of water to 100 parts by weight of the total of the carboxyl-containing radically polymerizable unsaturated monomer and the cyclic lactone; and carrying out dehydration under reduced pressure for removing low boiling components to form an ester bond between a by-produced water-initiated lactone oligomer and the carboxyl-containing radically polymerizable unsaturated monomer to thereby reduce a hydroxyl value to 5.0 mg KOH/g or less. Unsaturated lactone-derived polyester monomers having a terminal carboxyl group with practical quality can be produced at low cost.
    一种生产结构式(1)的不饱和内酯衍生聚酯单体的方法: 其中 R1、R2、R3、R4、R5、R6 和 R7 各代表一个取代基,该取代基选自氢原子、具有 1 至 10 个碳原子的取代或未取代的烷基、取代或未取代的芳基、取代或未取代的烷氧羰基、取代或未取代的烷氧基、取代或未取代的芳氧基和卤原子;n 表示 1 至 7 的整数;和 m 表示 1 至 100 的整数,方法是在常压下,使用酸性催化剂,在 1 至 50 份(重量)与 100 份(重量)含羧基的可辐射聚合的不饱和单体和环状内酯的总和存在下,使含羧基的可辐射聚合的不饱和单体与环状内酯反应;在减压下进行脱,以除去低沸点组分,从而在生成的引发内酯低聚物和含羧基可辐射聚合的不饱和单体之间形成酯键,从而将羟值降至 5.0 mg KOH/g 或更低。可以低成本生产具有末端羧基的不饱和内酯衍生聚酯单体。
