palladium supported on graphitic carbon nitride (Pd/g-CN) catalyzed carbonylative cyclization of 2-bromonitrobenzenes and alkynes has been developed for the expedite construction of quinolin-4(1)-one scaffolds. By using a low loading heterogeneous palladium catalyst, Mo(CO) as both the CO surrogate and the reductant, and nitroarenes as the nitrogen source, the reaction proceeded well to give a variety
开发了一种负载于石墨氮化碳 (Pd/g-CN) 上的钯催化 2-溴硝基苯和炔烃的羰基环化,用于加快构建 quinolin-4(1)-one 支架。通过使用低负载量的多相钯催化剂、Mo(CO)作为CO替代物和还原剂、硝基芳烃作为氮源,反应进展顺利,得到了多种从良好到优异的喹啉-4(1)-酮。产量。
