ABSTRACT:
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.
