Abstract The Wittig reactions of three stabilized phosphorus ylides with aldehydes in water were investigated. Most of the olefination reactions completed within 5–60 min in refluxing water in the presence of 1.2 M LiCl to afford the olefin products in 65–98% yields. It was found that the Wittig reactions of stabilized phosphorus ylides with aldehydes in water were faster than those carried out in
摘要 研究了三种稳定的磷叶立德与醛在水中的Wittig反应。大多数烯烃化反应在 5-60 分钟内在回流水中在 1.2 M LiCl 存在下完成,以 65-98% 的产率提供烯烃产物。发现稳定的磷叶立德与醛在水中的 Wittig 反应比在有机溶剂中进行的反应更快。
