A new class of multichelating bis(imino) pyridine compounds can promote the direct arylation of unactivated arene C-H bonds with aryl iodides and bromides in the presence of potassium tert-butoxide. This transition-metal-free process provides a promising system for cheap and efficient synthesis of biaryl structural units.
