Acrylonitrile → 4-Phenylcinnamonitrile

Participants

Reaction Steps

This compound is prepared from 10.83 g (50 millimols) of biphenyl-4-carboxylic acid chloride and 3.31 g (62.5 millimols) of acrylonitrile, the mixture being stirredfor 2 hours at 120° C. The crude product is extracted, in a Soxhlet extractor, with 100 ml of n-hexane, and is recrystallised from methanol. 3.83 g (37% of theory) of yellow crystals, melting point 43.7° C., are obtained. Analysis for C15H11N: calculated C 87.77%, H 5.40%, N 6.82%; found C 87.64%, H 5.34%, N 6.76%.
