Imines based on different and secondary amines were synthesized by reaction of acetylacetone with 2-amino-5-nitro phenol, adamantine amine, 1.7- diamino heptane and o-aminophenol. 2.4-bis (2-hydroxy-4-nitro-1-imino phenyl) pentane, 2.4-bis (2-imino admantyl) pentane, 2.4-bis(2hydrox y-1- iminophenyl) pentane and 1.5.13.18-tetraaza- 2.4.14.16- tetramethylcyclotetracosan- 1.4.13.16-tetraene have been characterized by EA, IR, 1HNMR and 13C-NMR.
