Transition Metal‐Catalyzed Site‐Selective CH Bond Arylation of Arenes/Heteroarenes Using Quinone Diazides

Abstract

Transition metal‐catalyzed direct introduction of phenol/naphthol moieties into the arene/heteroarene CH bonds has been studied using quinone diazides. Generally, the reactions proceed via CH insertions of metal carbenes or migratory insertion of metal carbenes. These arylation reactions are further discussed and extended with selected scope, limitations, and plausible mechanism. Interesting enantioselective reactions to provide stereogenic centers and axial chirality are also described. In this article, the summarized progress in the field of site‐selective arylations into CH bonds of arenes/heteroarenes using quinone diazide class of compounds under transition metal catalysis has been described.
