摘要: 测定了一系列N-甲酰基化合物的NMR波谱,对其一般特征进行了对比、讨论,尤其注意到由于C-N键的双键性而产生的异构体的性质以及氢键对于异构体的稳定作用.对于复杂的N-甲酰基化合物可根据简单的N-甲酰基化合物的谱图进行讨论.

Abstract: N-formyl compounds are useful fine chemicals and intermediates for medicines, pesticide, and herbicide. They are good solvents. We have obtained NMR spectra of a series of N-formyl compounds, general features of which are compared and discussed. Especially noticed the appearance of isomers due to double bond character of C-N bond and stabilization of hydrogen bond to the isomer. The spectra of the more complex N-formyl compounds are discussed in terms of the conclusions drawn from the spectra of simple compounds. To study the isomerism of N-formyl compounds, we have taken the temperature variation NMR technique. We have studied the ratio of isomers at different temperatures.It is our conclusion that the isomerism of N-formyl compounds is caused by double bond characer of C-N bond and hydrogen bond.
