Through this research we have well prepared the new [1, 4-Bis(2-phenyl-2, 3-dihydrobenzo-1, 3-oxazepine-4, 7dione)benzene(Z2)]is a seven-member ring that contains nitrogen, oxygen. The first step, prepared schiff bases N-benzylidenephenylenediamine F1 were synthesized by the condensation of equimolar quantity of primary aromatic amines p-Phenylenediamine with benazldehyde. The second step, percyclic reactions, between imine groups of schiff base F1 as two-membered components and cyclic acid anhydride phathalic anhydride as five membered component in dry benzene, were carried out to the synthesis of 1, 3-oxazepine derivatives Z1. The third step, prepared schiffbasesF2 were synthesized by the condensation of equimolar quantity of primary aromatic amines Z1 by with benazldehyde. Finally, prepared 1, 3-oxazepine derivatives Z2 by percyclic reactions. This preparing compounds were monitored and characterized by melting points, TLC, 1H-NMR, and FT.IR spectroscopy.
Schiff base, Phathalic anhydride, Oxazepine.
