Directed meta-Metalation Using Alkali-Metal-Mediated Zincation

Move over directed ortho‐metalation, here comes directed meta‐metalation. The unprecedented meta‐zincation of two anilides by a synergic mixed sodium/zinc dialkyl–amide base is presented. The orientation of the deprotonation of the anilides is remarkably switched to the meta site using this heterome...
