An eco-friendly and practical method for the clean preparation of 5-amino-1,2,4-thiadiazoles was developed. With WS as the semiconductor photocatalyst, both TEMPO and O (in air) as the redox catalysts, a variety of thiadiazoles were semi-heterogeneously formed in high to quantitative yields and could be easily collected by CPME extraction and rinsing. Furthermore, the catalytic system can be reusable
开发了一种环保实用的清洁制备5-氨基-1,2,4-噻二唑的方法。以WS作为半导体光催化剂,TEMPO和O(空气中)作为氧化还原催化剂,多种噻二唑以高定量产率半非均相形成,并且可以通过CPME萃取和漂洗轻松收集。此外,催化系统可重复使用至少5次反应。
