In this paper the use of a bubble column for a metal‐free, selective oxidation of α‐alkylthio‐imines to O,S‐acetals is presented. During the synthesis, which is straightforward to perform, the sulfides are oxidized to α‐alkoxy‐ or, respectively, α‐hydroxysulfide by adding activated carbon in the presence of atmospheric oxygen only. We show that the use of the bubble column, which is unusual on laboratory
在本文中,提出了使用鼓泡塔将α-烷硫基亚胺无金属选择性氧化为O,S-乙缩醛的方法。在易于执行的合成过程中,仅在大气中存在氧气的情况下,通过添加活性炭将硫化物氧化为α-烷氧基或α-羟基硫化物。我们表明,与常规实验室技术相比,在实验室规模上不常见的气泡塔的使用提高了反应效率。由于仅使用大气中的氧气进行氧化,因此该方法节省了成本,环保且安全。
