Aryl radical formation by aryl halide bond cleavage by a N-heterocyclic carbene catalyst
Aryl halides with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a chemical reaction that generates a highly reactive aryl.....»»
