Abstract In the present work we investigated the conformations of some N -mono-substituted propanamides of general formula CH 3 CH 2 CONHR, wherein R is chosen from n -(C 1 C 9 )alkyl, cyclo(C 3 C 6 )alkyl, some branched (C 3 C 6 )alkyl or phenyl. The amides were synthesised by the well known Schotten-Baumann reaction—acylation of the corresponding amines with propionyl chloride. On the basis of
摘要 在目前的工作中,我们研究了一些通式 CH 3 CH 2 CONHR 的 N-单取代丙酰胺的构象,其中 R 选自 n -(C 1 C 9 )烷基、环(C 3 C 6 )烷基,一些支链(C 3 C 6 )烷基或苯基。酰胺是通过众所周知的 Schotten-Baumann 反应合成的——相应的胺与丙酰氯的酰化。根据 N-单取代丙酰胺在四氯化碳、氯仿、二氯甲烷或 1:1.5 苯和四氯化碳混合物中的稀释溶液(浓度低于 10 -3 mol dm -3 )的 FTIR 数据,确定了NH伸缩带成立。对于光谱数据,分配了不同的构象异构体,并明确证明了其结构。这些结果与 1 H NMR 和 MS 数据非常吻合。
