A process for preparing substituted 2,2'-bipyridyl compounds and several compounds so prepared, the process comprising the steps of first selecting a substituted pyridine of the formula defined herein, then mixing a stoichiometric excess of the substituted pyridine with an amount of sodamide, causing the resultant mixture to be at a temperature sufficiently high to cause substituted 2,2'-bipyridyl formation, and isolating the substituted 2,2'-bipyridyl thereby formed. The new substituted 2,2'-bipyridyl compounds are selected from the group consisting of 4,4'-di-(5-nonyl)-2,2'-bipyridyl; 4,4'-di-(3-pentyl)-2,2'-bipyridyl; 6,6'-di-(3-pentyl)-2,2'-bipyridyl; 6,6'-di-(5-nonyl)-2,2'-bipyridyl; 4,4'-di-(cyclohexylmethyl)-2,2'-bipyridyl; 5,5'-di-(5-nonyl)-2,2'-bipyridyl; 4,4'-di-(3-phenylpropyl)-2,2'-bipyridyl; 4,4'-di-(4-tetrahydropyranyl)-2,2'-bipyridyl; 4,4'-di-benzyl-2,2'-bipyridyl; 6,6'-di-isoamyl-2,2'-bipyridyl; and 4,4'-di-(t-butyl)-2,2'-bipyridyl.
一种制备取代2,2'-联吡啶化合物的方法以及制备的几种化合物,该方法包括以下步骤:首先选择一个符合定义的取代吡啶的化合物,然后将过量的该取代吡啶与一定量的氨基钠混合,使得混合物在足够高的温度下形成取代的2,2'-联吡啶,并分离所形成的取代2,2'-联吡啶。新的取代2,2'-联吡啶化合物包括以下化合物:4,4'-二-(5-壬基)-2,2'-联吡啶;4,4'-二-(3-戊基)-2,2'-联吡啶;6,6'-二-(3-戊基)-2,2'-联吡啶;6,6'-二-(5-壬基)-2,2'-联吡啶;4,4'-二-(环己甲基)-2,2'-联吡啶;5,5'-二-(5-壬基)-2,2'-联吡啶;4,4'-二-(3-苯基丙基)-2,2'-联吡啶;4,4'-二-(4-四氢吡喃基)-2,2'-联吡啶;4,4'-二-苄基-2,2'-联吡啶;6,6'-二-异戊基-2,2'-联吡啶;以及4,4'-二-(叔丁基)-2,2'-联吡啶。
