Abstract(±)-1,1′-Binaphthalene-2,2′-diol (BINOL) was immobilized on polyethylene glycol (PEG) by means of triazole linkers, which were constructed by the [3+2] cycloaddition between azide and ethynyl fragments, preliminary incorporated into the molecules of these reactants. Treatment of these BINOL derivatives with phosphorus oxychloride leads to the corresponding PEG-immobilized 1,1′-binaphthalene-2,2′-diylphosphoric
