ABSTRACT Herein, we report a new and solvent-free methodology for the preparation of vinyl thioethers from terminal alkynes and thiols, using magnetite (Fe3O4) nanoparticles as a recyclable catalyst. With this greener method, the desired vinyl thioethers were achieved in good yields and with good stereoselectivity. In addition, the catalyst was easily recovered using a simple external magnet and reused
摘要在此,我们报告了一种新的无溶剂方法,用于从末端炔烃和硫醇制备乙烯基硫醚,使用磁铁矿 (Fe3O4) 纳米颗粒作为可回收催化剂。使用这种更环保的方法,以良好的收率和立体选择性获得了所需的乙烯基硫醚。此外,使用简单的外部磁铁很容易回收催化剂,并重新用于进一步的催化反应,直到第五次循环时活性没有显着损失。图形概要
