含苯并咪唑环N-酰腙衍生物的NMR研究
An NMR Study of a Novel N-Acylhydrazone Derivative Containing Benzimidazole Moiety
摘要
Abstract
With 1D NMR, 2D NMR and variable-temperature 1H NMR, the 1H and 13C NMR chemical shift of two isomers (E/trans and E/cis) of a new N-acylhydrazone derivative containing benzimidazole moiety (new compound 1), naming 2-[2-(4-methylphenoxymethyl)-1H-benzimidazol-1-yl]-N'-{[4-(dimetilamino)phenyl]methylene}acetohydrazide, were assigned. Coupling constants and tautomeric ratios of the isomers were determined. Experimental results showed that compound 1 in DMSO-d6 had both E/trans and E/cis isomers, and the ratio of the dominant E/cis isomer was 74.2%.关键词
