TLDR
In this article, a new class of bidentate ligands was prepared by a modular approach involving Rh-catalyzed C-H annulation reactions, and the resulting conformationally constrained ligands enabled electron-rich and sterically less hindered positions of electron rich arenes while promoting the facile oxidation of Pd(0) intermediates by oxygen.About:

Abstract: Transition-metal-catalyzed C-H functionalization is one of the fascinating scientific fronts in organic synthesis for the formation of conjugated arenes and has emerged as a benchmark to revolutionize the synthetic enterprise since past decades. In this realm, chelation-guided functionalization of C-H bonds using an exogenous directing group has received considerable attention recently for the expedient regioselective construction of C-C and C-heteroatom bonds as an efficient and sustainable alternative. This article outlines our contribution towards a wide variety of transformations that have been achieved by the directed C-H functionalization through the fine tuning of catalytic systems.
