A direct palladium-catalyzed C–H arylation method to synthesize biaryls from dicyanobenzenes has been developed. The reaction is selective towards C2-arylation of 1,3-dicyanobenzene and provides biaryls from both electron-rich and electron-poor aryl bromides containing para and meta substituents. A variety of functional groups are tolerated, and yields up to 83 % can be obtained. The methodology can
已经开发了一种直接钯催化的 C-H 芳基化方法,用于从二氰基苯合成联芳基化合物。该反应对 1,3-二氰基苯的 C2-芳基化具有选择性,并从含有对位和间位取代基的富电子和缺电子芳基溴化物提供联芳基化合物。可以容忍多种官能团,并且可以获得高达 83% 的产率。该方法可以扩展到其他缺电子苯甲腈的 C-H 活化。
