itriles) 4a–m were prepared via reaction of bis(2-propen-1-ones) 3a–g with malononitrile in the appropriate alcohol in the presence of KOH. The reaction was assumed to take place via Michael addition followed by cyclization due to the alkoxide nucleophilic attack at one of the nitrile groups. This assumption was substantiated by the reaction of ylidenemalononitrile 5 with the corresponding acetophenone
