The following imines: 1.8.13.20-tetraaza-13.3.6.18-diphenyl cyclotetracosan- 1.8.13.19- tetraene and butyradamantine, N.N’-di (admantyl) terephthimine and 1.5.14.18-tetraaza-2.4.15.17-tetramethylcyclotetracosan-1.8.13.19- tetraene based on dicarbonyl and amines were synthesized by reaction of dicarbonyl compounds and different amines. The imines have been characterized by EA (elemental analyses), IR, 1H- NMR and 13C-NMR.
