Aliphatic and aromatic Grignard reagents have been found to add to the double bond of 1,3-disubstituted benzimidazolium salts.The resulting substituted benzimidazolines were hydrolyzed and the aldehydes converted directly to their 2,4-dinitrophenylhydrazone derivatives.The scope and limitation of this synthesis are discussed.
