Abstract

Abstract: Ten 1 - phenylazonaphthalene dyes were synthesized, and their 1H,13C NMR spectra were recorded with emphasis on the criteria of azo and hydrazone tautomers on 1H,13 C NMR spectra. The electron effect and stereohindrance of substituents on the naphthalene ring, as well as the solvent effect on azo - hydrazone tautomerism were discussed.

摘要： 本文合成了10个1-苯基偶氮萘染料,并测定了其~1H、~（13）C NMR（核磁共振）谱,对~1H谱进行了归属,确定了2种异构体的判据,讨论了萘环上取代基的电子效应和空间障碍、溶剂的极性和pH值对偶氮-醌腙互变异构的影响。
