WebJan 31, 2024 · 楚加耶夫反应 （英语： Chugaev Elimination ）是一个由醇消除水制取烯烃的过程，与酯的热裂的机理类似，反应中不会发生碳正离子的重排。 反应以俄罗斯化学家Chugaev命名。 首先用醇钾与二硫化碳反应制取黄原酸盐，用碘甲烷甲基化，经过S N 2反应得到黄原酸酯。 然后黄原酸酯在约200°C时发生顺式消除，经由六元环过渡态，氢由β- … Web黄原酸酯消除也叫Chugaeve (楚加耶夫)消除反应，如图1所示，羟基化合物在碱性条件下和二硫化碳以及碘甲烷反应形成黄原酸酯，然后加热条件下发生分子内消除，经历六元环过渡态，顺式消除，得到烯烃，放出硫氧化碳和硫醇，该反应的优点是不发生碳架的异构和双键的迁移。 抢首赞 评论 Web黄原酸酯消除也叫Chugaeve(楚加耶夫)消除反应，如图1所示，羟基化合物在碱性条件下和二硫化碳以及碘甲烷反应形成黄原酸酯，然后加热条件下发生分子内消除，经历六元环过渡态，顺式消除，得到烯烃，放出硫氧化碳和硫醇，该反... graph related words
