The synthesis of the allyloxymethyl-functionalized crown ethers of type CH2=CHCH2OCH2[15-crown-5] (3a) and CH 2=CHCH2OCH2[18-crown-6] (3b) can be achieved by treatment of HOCH2[1
Polymeric and immobilized crown compounds, material for ion separation
Favre-Reguillon, Alain,Dumont, Nathalie,Dunjic, Branko,Lemaire, Marc
, p. 1343 - 1360 (2007/10/03)
We describe the synthesis of ionoselective polymers bearing different pendant crown ethers. The synthesis was applied to various macrocycles. We discuss the influence of macrocyclic cavity size and rigidity of the polymers on the extraction behavior. Accessibility of active sites can be achievied with immobilized functionalized polyurethanes chemically bound to an inorganic solid support, with no change of ionoselective properties.
Synthesis and Evaluation of New Polyurethane - Based Material for Ion Separation
Favre-Reguillon, Alain,Dumont, Nathalie,Dunjic, Branko,Lemaire, Marc

The polyaddition of macrocyclic diols with diisocyanates is an easy way to prepare ionselective polymers bearing pendant crown ethers.Those polymers can be readily immobilized on silicagel, with no change of ionselective properties.
A CONVENIENT SYNTHESIS OF CROWN AND AZACROWN ETHERS WITH PENDANT OXIRANE GROUP
Belohradsky, Martin,Stibor, Ivan,Holy, Petr,Zavada, Jiri
, p. 2500 - 2507 (2007/10/02)
Synthesis of 4,5-epoxy-2-oxa-1-pentylcrown (I) and N-(2,3-epoxy-1-propyl)azacrown ethers (II) from accessible materials is described.
