| titleOfInvention | METHOD OF OBTAINING SUBSTITUTED BIPHENYLS |
| abstract | A method for producing substituted biphenyls of the formula I wherein R is nitro, amino or NHR; R is CN, NO, halogen, C-C-alkyl, C-C-alkenyl, C-C-alkynyl, C-C-alkoxy, C-C- haloalkyl, C-C-alkylcarbonyl or phenyl; R-C-C-alkyl, C-C-alkenyl or C-C-alkynyl; m is 1 or 2; n = 0 to 3; which differs in that compound II in the presence of a base and a palladium catalyst selected from the group: a) a palladium-triarylphosphine or trialkylphosphine complex with palladium in the oxidation state of zero, b) a palladium salt in the presence of triarylphosphine or trialkylphosphine as complex ligand; or c) palladium metal optionally supported on a carrier, in the presence of triarylphosphine or trialkylphosphine in a solvent, reacts with diphenylboronic acid (III) |
