Synthesis of Salicylaldimine Schiff Bases with Benzo‐10‐aza‐15‐crown‐5 Pendant

Abstract

Abstract A series of azacrown ether substituted salicylaldimine Schiff bases 3a–c, 5a–c, and 6a–c have been synthesized by the condensation of salicylaldehyde with azacrown ether‐containing arylamine or amino‐compounds with azacrown ether‐containing salicylaldehyde from benzo‐10‐aza‐15‐crown‐5. The new structure was elucidated by spectral methods and confirmed by x‐ray crystallographic analysis.
