由苯并-15-冠-5经硝化、还原两步反应，制得4'，5'-二氨基苯并-15-冠-5(2)。后者与水杨醛或其取代衍生物缩合，合成了一系列新的冠醚化双Schiff碱化合物1a～1h，经元素分析、IR、^1^HNMR和MS确证了其结构。

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
