1,2,4-Thiadiazoles were efficiently synthesized in good yields through the oxidative dimerization of carbothioamides by using Oxone as a readily available, inexpensive, and environmentally safe oxidant. A similar reaction of phenylselenoamide led to the corresponding 1,2,4-phenylselenadiazole in high yield.
1,2,4-噻二唑通过硫代酰胺的氧化二聚反应以良好的产率高效合成,使用 Oxone 作为一种容易获得、价格低廉且对环境安全的氧化剂。苯基硒酰胺的类似反应以高产率得到相应的 1,2,4-苯基硒二唑。
