The representative mono- and dialkyl-substituted derivatives of 4-carbamoylimidazolium-5-olate (1) were synthesized unequivocally. On the basis of their spectral data for ultraviolet absorption spectra in acidic, basic and neutral solutions, we have found some spectral characteristics which make it facile to clarify the position of substituents.
明确地合成了4-氨基甲酰咪唑-5-油酸酯的代表性的单和二烷基取代的衍生物(1)。根据它们在酸性,碱性和中性溶液中的紫外线吸收光谱的光谱数据,我们发现了一些光谱特征,这些特征使澄清取代基的位置变得容易。
