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。
Olefins containing α-H can undergo free radical addition and free radical substitution reactions with bromine radicals. In this paper, propylene is used as an example to discuss the mechanism and competition of free radical addition and substitution reaction, so as to help the reader better understand the influence of reaction conditions on the dominant reaction and product.
