The chiral diphosphines, R- and S-(6,6'-dimethoxy-2,2'-bis(diarylphosphino)-1,1'-biphenyl, have been prepared with six steps from commercially available 3-bromoanisole by a concise synthetic route. This approach was also an efficient synthetic method for the biphenyl diphosphines with the different diaryl-phosphino group.

Key words: chiral ligand, synthesis, biarylenediphosphine
