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 adduct 6 described. By heating or photolysis 6 can be converted to the deeply colored polymethine 7. Complex formation constants with potassium ion by H-1-NMR-measurements have been determined.

An unexpected reaction of 1,5-bis(arylamino)-3-oxapentanes 4, 21 and 22 with diglycolyl dichloride gave 24-membered macrocyclic tetralactams 18, 23 and 24 respectively, in a reaction involving two molecules of each reactant (2:2 process). This was in contrast to closely related reactions of alpha,omega-bis(arylamino)alkylethers 5 and 6 with diglycolyl, triglycolyl and tetraglycolyl dichlorides which yielded the macrocycles 9-14 by reaction of one molecule of each reactant (1:1 process). The phenyl nuclei in 14 and 18 were formylated to give 34, 35 and 36. The aldehydes, 35 and 36 were condensed with a quinoxaline fluorophore to yield the diene 37 and the tetraene 38 respectively.
