(±) 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. Treat ment of these BINOL derivatives with phosphorus oxychloride leads to the corresponding PEG immobilized 1,1´ binaphthalene 2,2´ diylphosphoric acids. The latter efficiently cata lyze the Pudovik reaction and can be reused without loss of catalytic activity.
