  Reactions of CF3-substituted boranes with α-diazocarbonyl compounds

  摘要：

  Boranes substituted with a CF3-group can be generated from methyl boronic esters RB(OMe)(2) and Me3SiCF3/KF followed by treatment with Me3SiCl. These boranes are stable only in coordinating solvents, and due to the increased Lewis acidity of boron, react rapidly with alpha-diazocarbonyl compounds to give the products of transfer of the organic group from boron. Alkyl, aryl, vinyl, and alkynyl boronic esters can be used in this reaction. (C) 2011 Elsevier Ltd. All rights reserved,

  The present disclosure relates to a solid catalyst for propylene polymerization and a process for manufacture of a propylene polymer or copolymer using the solid catalyst, and provides a solid catalyst including carriers produced via a reaction between dialkoxy magnesium and metal halide, titanium halide, an organic electron donor, etc. and a process of manufacture of a propylene-based block copolymer via copolymerization of propylene-α-olefin using the solid catalyst. Particularly, internal electron donors including an ester group and an alkoxy group are used as two kinds of organic electron donors used in the present disclosure, and, thus, a block copolymer having high activity and excellent stereoregularity and a high rubber content via copolymerization with α-olefin can be produced using a solid catalyst system suggested in the present disclosure.

  本公开涉及一种用于丙烯聚合的固体催化剂以及使用该固体催化剂制造丙烯聚合物或共聚物的工艺，并提供了一种固体催化剂，包括通过二烷氧基镁与金属卤化物、卤化钛、有机电子供体等反应生成的载体，以及使用该固体催化剂通过丙烯-α-烯烃的共聚制造丙烯基嵌段共聚物的工艺。 特别是，本公开中使用了包括酯基和烷氧基在内的内部电子供体作为两种有机电子供体，因此，使用本公开中建议的固体催化剂体系，通过与α-烯烃共聚，可以生产出具有高活性和优异立体规整性以及高橡胶含量的嵌段共聚物。
