Abstract A facile one-pot, economical approach to 1,2,3-thiadiazol-5-ylureas was developed via selenium-catalyzed oxidative carbonylation of 1,2,3-thiadiazol-5-amine with a series of amines in one-pot manner in the presence of CO and O2. This approach is featured with cheap and easily available raw materials, cheap and reusable catalyst selenium, one-pot procedure, high atomic economy, simple operations
摘要通过硒催化1,2,3-噻二唑-5-胺与一系列胺的氧化羰基化反应,开发了一种简便,经济的1,2,3-噻二唑-5-基脲的制备方法。 CO和O2的存在方式。这种方法的特点是廉价且容易获得的原材料,廉价且可重复使用的催化剂硒,一锅法,高原子经济性,操作简单且无腐蚀性废物的排放。
