Abstract
A direct way to prepare cis,exo-hexahydromethano- or -ethanobiphenylene derivatives involving intramolecular aromatic C-H activation is reported. It consists of the palladium-catalyzed reaction of a rigid olefin with an aryl halide in dimethyl formamide in the presence of potassium carbonate.Keywords
