Participants

Reaction Steps

A sodium hydroxide solution (2.5 ml., 20%) is added to a solution of p-chlorobenzaldehyde (7.0 g., 0.05 mole) and 3,6-diphenyl-5-hexen-2-one (12.5 g., 0.05 mole) in ethanol (125 ml.) with stirring. The yellowish solid that separates on continued stirring is filtered, washed with cold ethanol, and air-dried, 14.35 g., m.p. 92°-95°C. Recrystallization from hexane gives material with m.p. 95°-96.5°C.
