Abstract

NEW MATERIAL:4'-Alkyl-4-fluorobiphenyls of formula I (R is 1W8C alkyl).
EXAMPLE: 4'-Pentyl-4-fluorobiphenyl.
USE: Displaying material for liquid crystal display elements, exhibiting smectic liquid crystal phase, and having low melting point. It has high mutual solubility to a wide variety of liquid crystal materials, and accordingly, is useful for the improvement of the properties of various liquid crystal compositions. It is also effective extremely as a liquid crystal agent for decreasing the viscosity.
PROCESS: The compound of formula I can be prepared, e.g. by (1) reacting a compound of formula II with hydroxylamine, (2) subjecting the resulting compound of formula III to Beckmann rearrangement to obtain a compound of formula IV, (3) hydrolyzing and diazotizing the compound of formula IV, (4) reacting the product with NaBF4 or HBF4, and (5) subjecting the resulting compound of formula V to Schiemann reaction.
