A mild, direct C–H arylation of 1-substituted tetrazoles to 5-aryltetrazoles is developed using a Pd/Cu cocatalytic system with readily available aryl bromides. The methodology avoids late-stage usage of azides and tolerates a wide range of functionalities.
使用Pd / Cu共催化体系和易于获得的芳基溴化物,可以将1-取代的四唑温和地直接进行CH芳基化为5-芳基四唑。该方法避免了叠氮化物的后期使用,并具有广泛的功能性。
