A new class of bidentate ligands was prepared by a modular approach involving Rh-catalyzedC–H annulation reactions. The resulting conformationally constrained ligands enabled the Pd-catalyzed C–H alkenylation at electron-rich and sterically less hindered positions of electron-rich arenes while promoting the facile oxidation of Pd(0) intermediates by oxygen. This newly introduced ligand class is complementary
