Syntheses of 1-alkyl-2-(substituted-2-pyridyl)benzimidazoles

1-α-Pyridinium acetophenone chloride 2 on reaction with 2-cinnamoylbenzimidazoles 3 followed by alkylation yields1-alkyl-2-(substituted-2-pyridyl) benzimidazoles 5. The latter could also be synthesized by direct reaction of 2 with 1-alkyl-2-cinnamoylbenzimidazoles 6 in accordance with the Kroehnke's pyridine synthesis.

Heterocyclic Analogues of 2,4,6-Triphenylpyrylium and 1-Benzyl-2,4,6-triphenylpyridinium

New pyrylium perchlorates with 2-thienyl, 2-benzothiazolyl, and 2-benzimidazolyl substituents at the 2-, 4-, and/or 6-positions, were synthesised and converted into the corresponding pyridines and 1-benzylpyridinium perchlorates.
