Iron sulfide generated in situ from elemental sulfur and iron was found to be highly efficient in catalyzing a redox/condensation cascade reaction between 2-amino/hydroxy nitrobenzenes and activated methyl groups. This method represents a straightforward and highly atom economical approach to 2-hetaryl-benzimidazoles and -benzoxazoles.
从元素硫和铁原位生成的硫化亚铁被发现能够高效地催化 2-氨基/羟基硝基苯和活化的甲基之间的氧化还原/缩合级联反应。该方法代表了一种直接且高度原子经济性的 2-杂芳基-苯并咪唑和苯并恶唑的合成方法。
