Abstract Two new bidentate phosphate ligands have been synthesized by Pd-catalyzed coupling reactions, characterized and evaluated. An efficient and simple Pd-catalyzed synthetic method for diarylmethane derivatives in good to high yields and two new diarylmethanes is reported for the first time. It provides a wide range of substrates and exhibits good functional group tolerance. This method has been
