Process for the preparation of thioethers by reacting a silylated thiol of the general formula:
wherein R represents an organic group and R1, R2 and R3 are the same or different and each represents an alkyl group having 1 to 4 carbon atoms, with an organic halide, sulphate or sulphonate in the presence of hexamethylphosphoric triamide as a solvent or co-solvent. The process is carried out under neutral conditions in aprotic solvents at a temperature between 0° and 150°C.
通式为:其中 R 代表有机基团,R1、R2 和 R3 相同或不同,且各自代表具有 1 至 4 个碳原子的烷基的硅烷化硫醇与有机卤化物、硫酸盐或磺酸盐在作为溶剂或助溶剂的六甲基磷酸三酰胺存在下反应制备硫醚的工艺。 该工艺在中性条件下,在温度为 0° 至 150°C 的钝溶剂中进行。
