Abstract

Abstract Procedures involving condensation of o-phenylenediamines with carboxylic acids, and reaction of bifunctional alkyl halides with bifunctional nucleophiles are described. Syntheses are reported of 2, 6-bis-(2-benzimidazyl)-pyridine, 1, 3-bis (2-benzimidazyl)-2- thiapropane, 1, 7-bis (2-benzimidazyl)-2, 6-dithiaheptane, 2-hydroxymethyl-5, 6- dimethylbenzimidazole, 2-chloromethyl-5, 6-dimethylbenzimidazole hydrochloride, 1, 7- ...
