Abstract
Abstract Starting from 4-chloropyridine and 2,6-dialkylphenoxides, 4-(3,5-dialkyl-4-hydroxyphenyl)pyridines are obtained via an electrochemically induced S RN 1 reaction using 2,4′ -bipyridine as a mediator (alkyl= pentyl, isopropyl, methyl). Quaternization of 4-(3,5-dipentyl-4-hydroxyphenyl)pyridine by linear alkyl halides, followed by deprotonation, gives (pyridinio-phenoxide) zwitterions.
