various thiols with alkyl halides under solvent-free reaction conditions using potassium fluoride on alumina (KF/Al2O3) as a solid catalyst has been investigated in detail with respect to three different modes of reaction activation (ultrasound irradiation, microwave irradiation, and conventional heating) for obtaining maximum yield of the thioether. The importance of KF/Al2O3 as a particularly efficient
摘要 在无溶剂反应条件下,使用氧化铝载氟化钾 (KF/Al2O3) 作为固体催化剂,通过各种硫醇与卤代烷的 S-烷基化制备硫醚,已经就三种不同的反应活化模式进行了详细研究。超声辐照、微波辐照和常规加热)以获得硫醚的最大产率。KF/Al2O3 作为一种特别有效的催化剂的重要性在所有三种反应活化模式中得到证实,尽管发现反应时间强烈依赖于活化模式。还发现硫醚的产率取决于相对于等摩尔量的两种反应物的固体催化剂的量。图形概要
