Synthesis of (Benzo -15- crown - 5) bis - schiff bases

Abstract

A new series of crowned bis - Schiff bases la～1h have been synthesized by condensation fo salicylaldehyde or its substituted derivatives with 4', 5'- diamino benzo -15- crown -5(2) prepared from benzo -15- crown -5 via dinitration followed by reduction in a breath. The structures of these crowned salophen type compouuds are consistent with data derived from elemental anlysis, IR, ^1H NMR and MS.

Key words: SCHIFF BASE, CROWN ETHER COMPOUNDS, NITRATION, REDUCTION, SALICYLIC ALDEHYDE, ELEMENTAL ANALYSIS, INFRARED SPECTROPHOTOMETRY, PROTON MAGNETIC RESONANCE SPECTROMETRY, MASS SPECTROGRAPHY

CLC Number:

O621
