Article abstract of DOI:10.1007/BF00557735

Liquid-crystal 2-cyano-5-pyridines were synthesized by the reaction of 1-dimethylamino-3-dimethylimmonia-2-propene perchlorates with 2-acetylfuran and subsequently through 2-furyl-5-pyrylium perchlorates and 2-(2-furyl)-5-pyridines by conversion of the latter to 5-alkyl(alkoxy)phenylpyridine-2-carboxylic acids, from which the cyano derivatives were obtained by the usual scheme through the amides.The intermediate arylfurylpyridines and arylpyridine-2-carboxylic acid imides also display liquid-crystal properties.
