chemical shifts for 14 isomeric monochloroesters of aliphatic carboxylic acids from propanoic acid to hexanoic acid have been determined. Comparisons are made with the literature values for methyl monochloro-octanoate isomers. Substituent effects for all positions are given. Characteristic IR absorption bands are presented and comparisons are made with regard to the isomeric structure. Connections
已确定脂肪族羧酸的14种异构一氯代酯从丙酸到己酸的13 C化学位移。与单氯辛酸甲酯异构体的文献值进行了比较。给出了所有位置的替代作用。给出了特征性的IR吸收带,并就异构体结构进行了比较。建议在观察到的红外吸收频率趋势与对13 C化学位移的某些“异常”氯取代基效应之间建立联系。考虑了这些化合物的1 H NMR谱。
