Abstract

Substituted heteroarenes are indispensable substructures of, among others, biologically active compounds and functional materials.1–3 In particular, strategies relying on direct C H bond functionalizations arguably constitute the most ecologically benign and economically attractive methods for their preparation.4 In recent years, various transition metal catalysts were devised for versatile direct arylations, alkenylations or alkynylations of heteroarenes by cleavages of unreactive C H ...
