A method of dehalogeno-dimerizing an aromatic halide compound substituted by at least one halogen atom substituted on the aromatic ring using a palladium catalyst on support in the presence of water, a reducing agent and a halogen acceptor is disclosed. The method is characterized by using the palladium catalyst on support immersed in a hydrohalogenic acid prior to the dehalogeno-dimerization reaction.
