Participants

Reaction Steps

0.390 G. of 4'-cyano-4-hydroxy-biphenyl are dissolved in 4.0 ml. of absolute pyridine and reacted with 0.424 g. of pelargonic acid chloride as in Example 1. The 0.722 g. of yellow crystals obtained according to the procedure described in Example 1 are dissolved in benzene and chromatographed on 40 g. of silica gel. Benzene elutes 0.617 g. of colorless crystals which are recrystallized from acetone-hexane up to constant melting point and clearing point. The pure 4'-cyano-4-biphenylyl nonanoate obtained melts at 43.2°-43.6° and has a clearing point of 74.0°. The compound is smectic up to 61.3°. UV (EtOH): ε272 = 26,900.
