Syntheses with Nitriles, LXXXVII. - Chromoionophores by Addition of N-Phenyl(aza-15-crown-5) to Reactive Dicyanomethylene Compounds

Addition of N-phenyl(aza-15-crown-5) (2) to dicyanomethylene compounds, i.e. the pyrazolylidenemalonitriles 1a-e, leads to the colorless (azacrownphenyl)(pyrazolyl)malonitriles 3a-e.Heating or photolysis of 3 eliminates hydrocyanic acid to give the deeply colored polymethines 4a-e.A corresponding reaction occurs between the indanylidenemalonitrile 5 and the crown ether 2 leading to adduct 6, which can be converted into the polymethine 7 by heating or photolysis.For evaluation of constants of the complex formation with sodium or potassium ions 1H NMR chemical shift measurements have been performed.
