- Abstract
3-Chloropropylsilica was reacted with Kriptofix 21 or 22 in the presence of triethylamine to form N-propylsilica Kryptofix 21 and Kriptofix 22. Then N2O4 was added to each of these polymers to chemisorb onto cavity of aza-crown ethers. These functionalized polymers were applied for the fast and simple oxidation of urazoles and 1,4-dihydropyridines, respectively.
