Sodium carbonate-promoted facile synthesis of 5-amino-1,2,4-thiadiazoles and 5-amino-1,2,4-selenadiazoles with elemental sulfur and selenium, respectively, was developed. This method was carried out with O2 in the air as the green oxidant, and it has several advantages, including low cost, low toxicity, and stable sulfur and selenium sources, good to excellent yields with water as the sole byproduct
开发了碳酸钠促进的 5-氨基-1,2,4-噻二唑和 5-氨基-1,2,4-硒二唑分别与元素硫和硒的简便合成方法。该方法以空气中的O 2为绿色氧化剂,具有成本低、毒性低、硫源和硒源稳定、收率优良、副产物为水、操作简单等优点。和广泛的底物范围。初步机理研究表明1,2,4-噻二唑环和1,2,4-硒二唑环的形成经历了不同的过程。
