Provided are a novel triphenyl phosphine derivative synthesized from a triphenylphosphine and a hydroxy-containing lactone; a palladium and a nickel complexes comprising the derivative as a ligand; and a process for preparing a biaryl derivative using the complex as a catalyst. A product can be easily separated from a catalyst or a phosphorus compound, and biaryl derivative can be synthesized in a higher yield, by using the complex of the present invention as a catalyst.
