• The reactivity of carbenes from photolysis of diazo-compounds towards carbon–hydrogen bonds. Effects of structure, temperature, and matrix on the insertion selectivity

  日期：——

  Direct and/or sensitized photolyses of diazo-acetate (1a) and -malonate (1b) in hydrocarbons and ether were investigated at various temperatures in order to learn more about the nature of the C–H insertion process and the structural factors governing positional selectivity within the matrix. Photolysis of the diazo-compounds in a rigid matrix resulted in a marked decrease in the insertion selectivity

  在各种温度下研究了重氮-乙酸盐（1a）和-丙二酸盐（1b）在烃和醚中的直接和/或敏化光解，以了解更多关于CH插入过程的性质以及控制位置选择性的结构因素的信息。在矩阵内。刚性基质中重氮化合物的光解导致插入选择性的显着降低，这可以解释为表明该基质强加了空间需求，尤其是在单线碳烯的直接C–H插入过程中。如在可比较的液相实验中所观察到的，在基质光解中添加敏化剂导致在（1a）情况下选择性的显着提高，但是在（1b）情况下导致选择性降低。这被解释为表明在这些条件下，激发三重态（1b）本身参与了C–H的插入。更广泛的温度研究表明，随着温度降低，：CHCO的C–H插入选择性不论反应相如何， 2 R都有规律地减少，而：C（CO 2 R） 2的液相增加，而固相减少。这种温度依赖性的差异可以通过假设单线态卡宾负责在整个研究温度范围内：CHCH 2 R的C–H插入，而单线态和三线态都参与：C（CO 2 R ） 2。

  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.
