【 摘 要 】

New derivatives of benzo-15-crown-5 with flexible appended N₂O unsymmetrical Schiff bases were prepared by a two step procedure which involves: (i) preparation of N₂O Schiff bases by condensation of hydrazine with salicylaldehyde, 3-methoxysalicylaldehyde or 2-hydroxy-1-naphtaldehyde and (ii) reaction of the resulting NH₂ functionalized compounds with 4’-formyl-benzo-15-crown-5.
