Proposed is a method of preparing polynuclear compounds, the method being characterized in that: a) an aromatic boron compound is reacted with b) an aromatic halo compound or an aromatic perfluoroalkyl sulphonate in the presence of C) a base, d) a nickel or palladium catalyst, e) a phosporus-containing ligand and f) a polyhydric alcohol, a sulphoxide or a sulphone. The method gives high yields, particularly in the coupling of chloro aromatic compounds. |
