补充资料:环烯
分子式:
CAS号:

性质:分子中含碳碳双键的脂环烃。它比相应的环烷烃含较少的氢原子。可分为单环烯、双环烯、桥环烯和稠环烯等。最简单的环烯是由三个碳原子组成的环丙烯,双键碳上的氢原子成顺式,它不稳定,在-80℃迅速聚合。从环壬烯开始有反式双键化合物存在。环烯的性质与链状烯烃相似,易发生亲电加成、聚合、氧化、还原等反应。小环环烯还可发生开环加成。共轭式环烯能发生双烯加成等反应。环烯及其衍生物广泛存在于自然界,工业上可由石油和动、植物组织中获取。实验室可由环醇、卤代环烷等发生消除反应,共轭二烯与烯或炔的环加成、光环化脱氢、芳环加氢等方法制取。具体的合成方法常因环烯结构不同有所不同。主要用于聚合和共聚,是生产尼龙8、尼龙12的原料。也用于合成精细化工产品。
