An unprecedented three-component coupling involving arynes, allyl bromides, and CO2 is described, providing efficient and facile access to structurally diverse ortho-brominated aryl esters. Unlike the conventional role played in organic synthesis as electrophiles, organic bromides served as nucleophiles in this reaction, affording a new approach to multicomponent reactions (MCRs) involving aryne intermediates
描述了涉及芳烃,烯丙基溴和CO 2的空前的三组分偶联,提供了结构上多样化的邻溴代芳基酯的有效而便捷的途径。与有机合成中作为亲电试剂的常规作用不同,有机溴化物在该反应中充当亲核试剂,为涉及芳烃中间体的多组分反应(MCR)提供了新方法。另外,Hammett分析表明存在两种反应机理,这取决于所用肉桂基溴化物的电子性质。
