反応手順
6.7 g of terephthaldehyde are reacted with 12.8 g of m-diethylphosphonomethylbenzonitrile (99.2%) in accordance with Example 1. The reaction temperature is kept initially at 0°-5° C. for 1/2 hour and allowed to rise overnight to 22° C. 3-Cyanostilbene-4'-aldehyde containing 2% of 1,4-di(m-cyanostyryl)benzene is obtained in a yield of 8.0 g after working up as described in Example 1, but without dilution with water.
