Abstract
NEW MATERIAL:An optically active amyl ester of a 4'-alkyl-4-biphenylcarboxylic acid shown by the formula (R is 1W10C alkyl).
EXAMPLE: An optically active amyl ester of 4'-n-pentyl-4-biphenyl-carboxylic acid.
USE: An auxiliary material for display elements. An optically active compound having chemical and optical stability. The addition of the ester to a nematic liquid crystal provides easily a chiral nematic liquid crystal.
PROCESS: A 4'-alkylbiphenylcarboxylic acid is reacted with thionyl chloride to give an acid chloride, which is reacted with a sloution of active (-)amyl alcohol in pyridiene, to give a compound shown by the formula.
