Formation of methylenebis(4'-benzo-15-crown-5) (I) has been accomplished by heating a mixture of benzo-15-crown-5 and N,N-aminodiacetic acid in polyphosphoric acid (PPA). The reaction pathway probably involves reaction of N,N-diacetic acids with PPA to form the corresponding anhydrides, followed by release of CO2 and CH2O thermally. As a result, I was formed by the condensation of CH2O with benzo-15-crown-5 under the action of PPA.
