Acetone → 1,4-Pentadien-3-one, 1,5-bis[4-(diethylamino)phenyl]-

Participants

Reaction Steps

In 25 ml of anhydrous ethanol were dissolved 17.7 g of p-diethylaminobenzaldehyde and 2.9 g of acetone, and 1.5 ml of 10% aqueous NaOH was added dropwise to the resulting solution, after which the resulting mixture was subjected to reaction under reflux for 8 hours. The reaction mixture was cooled, and the crystals thus precipitated were collected by filtration and then recrystallized from toluene, to obtain 7.7 g of 1,3-bis(4'-diethylaminobenzal)acetone (m.p. 168° C.).
