Reaction Steps
A 1.5 g sample of p-nitrobenzaldehyde and 1.7 g of p-nitrobenzylcyanide were dissolved in 5 ml of hot ethanol, and 0.05 ml of pyridine was added. The mixture was heated for 10 minutes. After cooling overnight, the precipitated crystals were filtered and recrystallized from a mixture of acetone and ethanol to obtain 1-cyano-1,2-bis(p-nitrophenyl)ethylene having a melting point of 216.5°-217.5° C.
