The room temperature palladium-catalyzed cross-coupling of aromatic and heteroaromatic halides with Reformatsky reagents derived from 1-bromocyclopropanecarboxylates provides an exceptionally mild method for enolate α-arylation. The method is tolerant of a wide range of functionalities and dramatically shortens many of the existing routes to access widely used 1,1-disubstituted cyclopropanecarboxylate
室温钯催化的芳香族和杂芳香族卤化物与衍生自1-溴环丙烷羧酸盐的Reformatsky试剂的交叉偶联为烯醇化α-芳基化提供了一种异常温和的方法。该方法具有广泛的功能性,并且大大缩短了许多现有的获得广泛使用的1,1-二取代的环丙烷羧酸酯衍生物的途径。
