Selective aryl coupling via palladacycles: a new route to m-alkylbiphenyls or m-terphenyls

Abstract
O-Alkyl- or o-aryl-substituted arylnorbornylpalladium chloride complexes react with aromatic iodides in dimethylformamide (DMF) via palladacycles to give after hydrogenolysis m-alkylbiphenyls or m-terphenyls.
