Synthesis of Isomeric Dinitro and Diamino Derivatives of Polycyclic Crown Ethers: Dibenzo-18-crown-6 and Dibenzo-24-crown-8

Specific features of the synthesis of polycyclic crown ethers dibenzo-18-crown-6 and dibenzo-24-crown-8 and their dinitro and diamino derivatives have been studied. A mixture of isomers of dibenzocrown ether derivatives was obtained and separated. The spectral and thermal characteristics of the synthesized compounds and the kinetics of synthesis of dibenzo-24-crown-8 by the two-component condensation of pyrocatechol with 1-chloro-2-[2-(2-chloroethoxy)ethoxy]ethane in an alcoholic medium in the presence of a KOH template agent were studied.

Benzo- and dibenzo-crown ethers substituted with (azulene-1-yl) azo chromophores. Synthesis and properties

Colored benzo- and dibenzo-crown ethers with (azulene-1-yl) azo chromophores(s) at benzo ring(s) were synthesized in good yields starting from the amines of the benzo- and dibenzo-crown ethers which were diazotized and coupled with azulenes. The obtained crown ethers were characterized and several properties of the generated new dyes were investigated (electronic and NMR-spectra, as well as pKa values, the lipophilicity and the coordination with metal cations).

Nitration of benzo crown ethers with potassium nitrate in polyphosphoric acid

A general method for the nitration of benzo crown ethers with potassium nitrate in polyphosphoric acid has been developed. Mono- and dinitro derivatives of benzo-12-crown-4, benzo-15-crown-5, dibenzo-18-crown-6, and dibenzo-24-crown-8 have been prepared. The role of complex formation in the regioselective tendency for the nitration of dibenzo-18-crown-6 has been demonstrated.
