SYNTHESIS OF 5-ALKYL-2-(4-CYANOPHENYL)PYRIDINES

The synthesis of 5-alkyl-2-(4-cyanophenyl)pyridines was realized by the keto vinylation of N-4-alkenylpiperidines with 4-bromophenyl β-chlorovinyl ketone followed by cyclization of the obtained 4-piperidino-3-alkyl-1-p-bromobenzoyl-1,3-butadienes to 5-alk

Synthesis and Properties of 5-Alkyl-2-(4-Cyanophenyl)Pyridines

The synthesis, physico-chemical and electro-optical properties of new nematic liquid crystal materials with a positive dielectric anisotropy - the 5-alkyl-2-(4-cyanophenyl)pyridines - are reported.The transition temperatures, transition enthalpies, dielectric optical, and visco-elastic properties, and also the threshold voltages and response times of the twist-effect have been measured for 2-7 homologous and binary mixtures of 5-alkyl-2-(4-cyanophenyl)pyridines (PR) containing the pentyl and heptyl components in the molar proportion 40:60.The results obtained are compared with the properties of 4-cyano-4'-n-alkyl-biphenyls (CB) and 5-n-alkyl-2-(4-cyanophenyl)pyrimidines (PY).
