efficient and odourless procedure for a one-pot synthesis of thioesters by the reaction of benzoic anhydrides, thiourea and various organic halides (primary, allylic, and benzylic) or structurally diverse, electron-deficient alkenes (ketones, esters, and nitriles) in the presence of Et3N has been developed. In this method, thiobenzoic acids were in situ generated from the reaction of thiourea with benzoic anhydrides
一种高效、无味的方法,通过苯甲酸酐、硫脲和各种有机卤化物(伯卤化物、烯丙基卤化物和苄基卤化物)或结构多样的缺电子烯烃(酮、酯和腈)的反应来一锅合成硫酯。 Et3N 的存在已被开发出来。在该方法中,硫脲与苯甲酸酐反应原位生成硫代苯甲酸,苯甲酸酐与缺电子烯烃进行共轭加成或与卤代烷发生亲核置换反应。
