Abstract
Peculiarities of benzo-15-crown-5 (I), [3.3]dibenzo-18-crown-6 (II), and [4.4]diben zo-24-crown-8 (III) nitration by the dilute nitric acid and the mixture HCl-HNO3(4:1, «aqua regia») at room temperature are discussed. It was revealed that the «reactivity» of studied crown ethers (symbatically/antisymbatic to their hydrophili ci ty/lipophilicity) is variated as follows: I>> III> II.
