Ortho C−H Functionalizations of 2‐Aryl‐2H‐Indazoles.

C−H Functionalization is ubiquitously considered as a powerful, efficient and handy tool for installing various functional groups in complex organic heterocycles in an easier and step‐economic way. Similarly, indazole is endowed as a potent heterocycle and is eminent for its profound impact in biological, medicinal and industrial chemistry. In this scenario, C−H functionalization at the selective ortho position of 2‐arylindazole in assistance of a metal catalyst is also becoming an appealing approach in synthetic organic chemistry. This review addressed the recent findings and developments on ortho C−H functionalization of 2‐aryl‐2H‐indazazoles with literature coverage extending from 2018 to May 2022. [ABSTRACT FROM AUTHOR]
