Synthesis and Characterization of New Bis-Schiff Bases Linked to Various Imide Cycles

This research includes the synthesis of new bis-Schiff bases linked to different imide cycles. There were some steps involved in novel Schiff with succinimide, phthalimide, tetrachlorophthalimide, and tetrabromophthalimide The first step preparation 4,4`-bis[(4-aminophenyl) methyl benzylidene]tolidine (1) via condensation reaction 3,3'-dimethyl-(1,1'-biphenyl)-4,4'-diamine 4-amino acetophenone. In second step, compound 1 reacted various cyclic anhydrides, affording bis-amic acid 2-5. third products 2-5 dehydrated using fusion method produce target bis-imidyl 6-9. work also base 10 directly by 1,8-naphthalic anhydride. prepared compounds characterized depending on their FT-IR, 1H NMR, 13C NMR spectra. newly synthesized are expected be very active biologically since molecules essential components two groups (imine imide).
