技术领域
该专利涉及有机合成、药物合成、有机化工等研究领域，具体的方法就是β-亚磺酰基酯和苄基三氟甲烷磺酸季铵盐进行的无过渡金属催化一步合成苄基硫醚类化合物。

我们开发了苄基三氟甲烷磺酸季铵盐与β-亚磺酰基酯在强碱的作用下一步合成苄基硫醚的合成方法，即在乙腈中，在KOH的作用下，苄基三氟甲烷磺酸季铵盐与β-亚磺酰基酯合成苄基硫醚；在使用手性的苄基三氟甲烷磺酸季铵盐时，能够得到构型翻转的目标产物，且手性值保留得非常好。
尽我们所知，未见与本申请相同的文献报道。
发明内容
本发明提供一种无金属催化苄基硫醚的合成方法。
本发明公开的苄基硫醚的合成方法均一步完成，在有机溶剂乙腈中，无过渡金属催化，仅在碱KOH的作用下β-亚磺酰基酯和苄基三甲基铵盐一步合成苄基硫醚，反应通式如下。其中R可以是芳基、杂芳基、烷基。此外，部分季铵盐苄位具有手性碳，合成的产物相应地具有手性。
