cobalt catalyst, synthesis of various substituted pyrrole derivatives is reported. In this methodology, pyrroles were synthesized through coupling between nitroarenes and alkenyl diols in a tandem manner. Among all the heterogeneous catalysts Co(OAc)2-CC-800 displayed the highest catalytic activity. Preparative scale synthesis of pyrroles and synthesis of anti-tubercular agent 5-(4-(1H-pyrrol-1-yl)phenyl)-1
据报道,使用生物废物咖啡因碳负载的多相钴催化剂合成了各种取代的吡咯衍生物。在该方法中,通过硝基芳烃和烯基二醇以串联方式偶联合成吡咯。在所有多相催化剂中,Co(OAc) 2 -CC-800 表现出最高的催化活性。吡咯的制备规模合成和抗结核剂 5-(4-(1H-pyrrol-1-yl)phenyl)-1,3,4-oxadiazole-2-thiol 的合成揭示了该协议的实际适用性。进行了几次动力学实验和哈米特研究,以了解这种转变的可能机制和电子效应。
