AbstractA simple and efficient one-pot synthesis was developed for the preparation of S-alkyl thiolcarbamates from xanthogenate without catalyst using water as a solvent. The water can be recycled after removal of the product. The significant features of this protocol are: operational simplicity, mild reaction conditions, recycling of solvent and high product yields. Starting basic alkyl xanthogenate
摘要开发了一种简单有效的一锅合成法,用于在不使用催化剂的情况下使用水作为溶剂由黄原酸酯制备S-烷基硫代氨基甲酸酯。除去产品后可以将水回收。该协议的显着特点是:操作简便,反应条件温和,溶剂循环利用和高产品收率。起始碱性黄原酸烷基酯与烷基硫酸铵(芳基硫酸铵)和过氧化氢(摩尔比为1:0.55:1)在水中在40°C下反应1 h,然后在70–110°C下额外加热1–2.3 H。使用10%摩尔过量的硫酸铵可获得良好至优异的收率。 图形概要
