and stereoselective rearrangement of allenic alcohols to (E,E)-1,3-dien-2-yl triflates and chlorides was developed under metal-free conditions. Subtle electronic effects of the alkyl and aryl substituents on the carbon bearing the hydroxyl group has a profound impact on the reaction rate and efficiency such that vinyl triflates were obtained from electron-deficient substrates and trimethylsilyl triflate
在无金属条件下开发了烯丙醇至(E,E)-1,3-dien-2-基三氟甲磺酸酯和氯化物的一般和立体选择性重排。烷基和芳基取代基在带有羟基的碳上的细微电子效应对反应速率和效率产生深远影响,因此,三氟甲磺酸酯是从缺电子的底物和三甲基甲硅烷基三氟甲磺酸酯中获得的,而氯乙烯则是由富含电子的电子生成的底物和三甲基甲硅烷基氯。
