摘　　要：合成了９个２－羟基－１－萘醛缩苯胺类Ｓｃｈｉｆ碱化合物，通过ＩＲ、１ＨＮＭＲ和１３ＣＮＭＲ测定，对其波谱进行了研究。在１ＨＮＭＲ谱中，得出酚羟基质子的化学位移值与苯环上的间位和对位取代基的Ｈａｍｍｅｔ常数有很好的线性关系：δ＝１４．９６－２．２６σ，ｒ＝０．９７，ｎ＝８。证明了此类Ｓｃｈｉｆ碱化合物的结构为烯醇亚胺结构。Nine Schiff base compounds from 2 hydroxy 1 naphthaldehyde with aromatic amines were prepared.The spectral property were studied by IR、 1H NMR and 13 C NMR spectra.There was a good linear relation between the chemical shift of hydroxylic proton and Hammett substituent constants in 1H NMR spectra:δ=14.96 2.26σ r=0.97 n=8. The structure of the Schiff bese compounds was proved to be enol imine.
