The present paper describes the preparation by conventional methods (when not available commercially) and the pKa-determination of the α-, β- and γ-isomers of pyridylethanamide, 3-pyridylpropanamide. 4-pyridylbutanamide, 5-pyridyl-pentanamide, pyridylmethanol, 2-pyridylethanol, 3-pyridylpropanol, 4-pyridyl-butanol, 5-pyridylpentanol, pyridylmethylamine, 2-pyridylethylamine, 3-pyridyl-propylamine, 4-pyridylbutylamine
本文件描述了通过常规方法制备(当不市售)和p ķ一个所述的α--determination,β-和pyridylethanamide的γ -异构体,3- pyridylpropanamide。4-吡啶基丁酰胺,5-吡啶基戊酰胺,吡啶甲醇,2-吡啶基乙醇,3-吡啶基丙醇,4-吡啶基丁醇,5-吡啶基戊醇,吡啶基甲胺,2-吡啶基乙胺,3-吡啶基-丙胺,4-吡啶基丁胺和5-吡啶基戊胺。尽管场效应解释了p K a随链长变化的许多变化,但在某些甲基和乙基同系物中,明显的感应效应是有效的。在P ķ一在属于α系列的一些较低的同系物中,分子内H键的递减影响也是明显的。
