摘要

Abstract The synthesis and spectroscopic properties of the three isomers of nitrocaffeic acid are described. The three pK as of each isomer were measured by UV–visible spectroscopy. The comparison of the UV–visible spectra of nitrocaffeic acids and those obtained from the reaction of caffeic acid with reactive nitrogen species led to the conclusion that the nitration of caffeic acid with acidic nitrite does not significantly occur and confirmed the absence of ...
