Double‐armed crown ether aldehydes (1–3) were synthesized from the reaction of 2 equiv salicylaldehyde, 4‐hydroxy‐3‐methoxybenzaldehyde (vanillin), and 3‐hydroxy‐4‐methoxybenzaldehyde (iso‐vanillin) with 4′,5′‐bis(bromomethyl)benzo‐15‐crown‐5. New crown ethers imine compounds (4–9) were synthesized by the condensation of corresponding crown ether aldehydes (1–3) with 4‐amino‐1,2‐dihydro‐1,5‐dimethyl‐2‐phenyl‐3H‐pyrazole‐3‐one and 2‐furan‐2‐yl‐methylamine. Sodium complexes (1a–9a) of the crown compounds form crystalline 1:1 (Na+:ligand) stoichiometries and were also synthesized. The structures of the crown ether aldehydes (1–3), imine compounds (4–9), and complexes (1a–9a) were confirmed on the basis of elemental analyses, IR, 1H and 13C NMR, and mass spectrometry. © 2013 Wiley Periodicals, Inc.

“…Although bi-dentate chelating compounds were investigated in plentiful studies, only one of them has been reported on benzo crown ether-4-antipyrine containing Schiff base group. Regarding this property, Hayvali 80 , 2009, reported the preparation of a novel crown antipyrine azomethine (Figure 20).…”

In latterly years, an interest in the synthesis of crown ether Schiff bases and their Complexes has been increased, due to the significance and broadly the uses of these compounds in various fields. In the present review paper outline extensive recent advances literature survey on the crown ether including azomethine gathering and their complexes with the tough and easy granter atoms, has been reconsidered. Assertiveness has been done on element complexation with crown ether holding Schiff bases to enable the researchers to procure valuable information of the chelating activity of crown ether containing azomethine gathering and their enforcement.

“…6,[13][14][15] The crown ether center can generate stable complexes with alkali metal and alkaline earth metal cations, while the substituted side center can form transition metal complexes. 12,[16][17][18][19][20][21][22][23] Their complexing properties make crown ethers especially interesting and useful compounds in biological research and in chemistry. [24][25][26][27][28][29][30][31] The ion complex-carrying ability of crown ethers results in them resembling natural ionophores (such as gramicidin).…”

New aldehyde- and halogen- (Cl, Br, I) substituted double-armed benzo-15-crown-5 derivatives are synthesized by the reactions of 4′,5′-bis(bromomethyl)benzo-15-crown-5 with 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, or 5-iodosalicylaldehyde. The sodium and potassium complexes are obtained by reaction of crown ether with sodium perchlorate and potassium iodide, respectively. Novel Schiff base compounds containing three groups of benzo-15-crown-5 are obtained from the condensation of aldehydes with 4′-aminobenzo-15-crown-5. The structures of all compounds are elucidated by elemental analysis, 1H, 13C NMR, IR, and mass spectra. The antifungal and antibacterial effects of the synthesized ligands are evaluated against pathogenic microorganisms and show varying degrees of inhibitory effects against the growth of different pathogenic strains.
