Abstract: 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.
Keywords: Schiff base ligands; crown ethers; hetero-binucleating ligands; hydrazine; salicylaldehyde Schiff base ligands; crown ethers; hetero-binucleating ligands; hydrazine; salicylaldehyde
