alkynes promoted by KF/Al2O3, using glycerol as recyclable solvent. This improved method furnishes selectively the corresponding anti-Markovnikov vinyl sulfides in good to excellent yields starting from terminal alkynes and aliphatic or aromatic thiols. The irradiation with microwaves facilitated the procedure and accelerates the reaction. The catalytic system and the glycerol can be re-used up to four
描述了一种新的、清洁的、有效的协议,用于由 KF/Al2O3 促进的末端炔烃的氢硫醇化,使用甘油作为可回收溶剂。这种改进的方法从末端炔烃和脂肪族或芳香族硫醇开始,选择性地提供相应的反马尔科夫尼科夫乙烯基硫化物,产率良好至极好。微波辐射促进了该过程并加速了反应。催化系统和甘油可以重复使用多达四次,无需事先处理,并且具有相当的活性。
