Summary

An improved synthesis of 7,16-diphenyl-1,4,10,13-tetraoxa-7,16-diaza-cyclooctadecan (5) is presented and the reaction with 4-dicyanomethylene-3-methyl-1-phenyl-2-pyrazolin-5-on to the colorless adduct6 described. By heating or photolysis6 can be converted to the deeply colored polymethine7. Complex formation constants with potassium ion by1H-NMR-measurements have been determined.
