Abstract
PURPOSE: To obtain the titled compound extremely useful as an intermediate for synthesizing phenylalanine by a simple operation smoothly and readily, by reacting benzene with 2,3-dichloropropionitrile in the presence of a catalyst.
CONSTITUTION: Benzene is reacted with 2,3-dichloropropionitrile in the presence of a catalyst (e.g., SbCl5, MoCl5, etc.), to give α-chlorohydrocinnamnitrile. 2,3- Dichloropropionitrile, a starting material, is obtained readily by adding Cl2 to acrylonitrile. An amount of the catalyst is 0.1W3mol based on 1mol 2,3-dichoropropionitrile. The addition of Lewis acid, hydrochloric acid, silica gel, etc. as a cocatalyst improves the yield. The reaction temperature is 40W150°C.
