Synthesis of sulfonylmethylated and cyanomethylated nitrobenzocrown ethers. Potential reagents for colourimetric analysis of alkali cations
Makosza,Krylowa
, p. 1409 - 1410 (1994)
Sulfonylmethyl and cyanomethyl derivatives of nitrobenzocrown ethers were prepared via vicarious nucleophilic substitution of hydrogen. These compounds form highly coloured internal potassium salts soluble in nonpolar solvents.
