摘要:

含有α-H的烯烃可以与溴自由基发生自由基加成和自由基取代反应。本文以丙烯为例,论述了自由基加成和取代反应的机理和竞争关系,从而帮助读者更好地理解反应条件对优势反应及产物的影响。

关键词: 丙烯, 溴自由基, 自由基加成, 自由基取代, 竞争关系

Abstract:

Alkenes with α-H can react with bromine radical via both free radical addition and free radical substitution. In this paper, the mechanisms of the free radical addition and free radical substitution and the competition between these two reactions were discussed using propylene as an example to illustrate effects of reaction conditions on the major reaction and products.

Key words: Propylene, Bromine radical, Free radical addition reaction, Free radical substitution reaction, Competition
