SYNTHESIS OF 4-ALKYL-4'-CYANOBIPHENYLS

Liquid crystals of the 4-alkyl-4'-cyanobiphenyl group were synthesized without the use of copper cyanide. 4-Alkyl-4'-formylbiphenyls and the 4-formyloximes of 4'-alkylbiphenyl, which possess a liquid-crystalline state, were isolated.Beginning with the pentyl homolog, they form an enantiotropic nematic phase, and beginning with octyl homolog they also form a smectic meso phase.

NEW SIMPLE METHOD FOR OBTAINING 4-n-ALKYL-4 prime -CYANOBIPHENYLS.

A new method is described of obtaining 4-n-alkyl-4 prime -cyanobiphenyls from biphenyl. First biphenyl is acrylated and the resulting ketone is reduced in conditions of the Huang-Minlon reaction; next the obtained 4-n-alkylbiphenyl is converted to 4-n-alkyl-4 prime -iodobiphenyl which readily reacts with copper cyanide giving the required nitrile with a good yield.
