The reaction of some alkenols with tetrachloromethane in the presence of a radical initiator was investigated. Regarding the effects of structural features of the starting alkenol (number and position of methyl substituents at the double bond and at the carbinol carbon atom, constitutional relationship between the double bond and the hydroxyl group) there are two possible competing reactions: addition
在自由基引发剂的存在下,研究了一些烯醇与四氯甲烷的反应。关于起始烯醇的结构特征的影响(双键和甲醇碳原子上的甲基取代基的数量和位置,双键与羟基之间的构成关系),存在两种可能的竞争反应:加成和环化。在最简单的链烯醇(无取代基和较远的双键)的情况下,会发生加成;单-和二取代的仲和叔Δ 4 -和Δ 5 -alkenols以高产率环化,得到相应的环醚。
