The reaction of isoprene bromohydrin (1-bromo-2-methyl-3-buten-2-ol) (1) with ethyl-, propyl- and butyllithium in the presence of copper (I) iodide leads to the exclusive formation of the vinyl group migrated 2-alkyl-4-penten-2-ols (3d–3f), in contrast to the reaction with methyl-, phenyl- and benzyllithium, which yields the corresponding 2-methyl-4-substituted-2-buten-l-ols (2a–2c).
在碘化铜 (I) 存在下异戊二烯溴醇 (1-bromo-2-methyl-3-buten-2-ol) (1) 与乙基-、丙基-和丁基锂的反应导致独家形成乙烯基基团迁移了 2-烷基-4-戊烯-2-醇(3d-3f),与甲基-、苯基-和苄基锂的反应相反,后者产生相应的 2-甲基-4-取代-2-丁烯-l -ols (2a–2c)。
