A process is described for the preparation of arylpyridine compounds by aryl-aryl cross-coupling reactions between a halopyridine and an arylmagnesium halide carried out in the presence of a catalytic amount of a zinc salt and a catalytic amount of palladium. The zinc salt is preferably selected from ZnC12, ZnBr2 and/or Zn(OAc)2 while the palladium is preferably used in the form of Pd(PPh3)4 or Pd(OAc)2 + 4 PPh3. The reaction can also be carried out in the presence of bidentate phosphines, such as, for example, 1,3-bis(diphenylphosphine)propane or 1,4-bis(diphenylphosphine)-butane. It is thus possible to obtain molar yields higher than 97% (calculated relative to the halopyridine) and a catalyticity of more than 2000.
