It has been found that syntheses of thioethers and thioesters of aliphatic, aromatic and heterocyclic compounds, bearing thiol groups, can be accomplished with alkyl, acyl, benzyl or benzoyl halides in acetonitrile and cesium fluoride–Celite. In this manner, compounds like ethanethiol, 1-pentanethiol, thiophenol, 4-methoxythiophenol, 4-nitrothiophenol, and 2-mercaptobenzoxazole, 2-mercaptobenzothiazole
已经发现,带有硫醇基团的脂肪族,芳香族和杂环化合物的硫醚和硫酯的合成可以用烷基,酰基,苄基或苯甲酰基卤化物在乙腈和氟化铯-硅藻土中完成。以这种方式,化合物如乙硫醇,1-戊硫醇,苯硫酚,4-甲氧基硫酚,4-硝基硫酚和2-巯基苯并恶唑,2-巯基苯并噻唑和2-巯基-2-噻唑啉可以成功地被烷基化,酰化,苄基化或苯甲酰化。该方法对于制备硫醚和硫酯是方便,有效和实用的。
