and aliphatic thiols using isopropenyl acetate as a cheap and convenient acetylating agent. During our tests, we also investigated the differences between the activities of metal triflates and triflic acid as catalysts in the acetylation of thiols. Finally, the potential of our concept has been increased by the implementation of Nafion as a heterogeneous catalyst for S-acetylation of thiols.
本文证明了使用
乙酸异丙烯酯作为廉价便捷的乙酰化剂,可以通过HOTf催化的芳香族和脂肪族
硫醇的S-乙酰化,高效,温和和
化学选择性地合成各种
硫酯。在我们的测试过程中,我们还研究了
三氟甲磺酸盐和
三氟甲磺酸作为
硫醇乙酰化催化剂的活性之间的差异。最后,通过将Nafion用作
硫醇S-乙酰化的非均相催化剂,我们的概念的潜力得到了提高。
