✦ Synopsis

Abstract

Straight to the point: The direct 3‐ or 4‐arylation of pyrrole derivatives through CH bond activation proceeds in moderate to good yields using Pd(OAc)~2~ as catalyst. In contrast to classical coupling procedures, the preparation of an organometallic derivative is not required and the major by‐products are AcOH/KBr instead of metallic salts.magnified image
