Chapter 16, Problem 16.69(choose chapter or problem)
As we saw in Chapter 6, carbon-carbon double bonds are attacked by electrophilesbut not by nucleophiles. An exception to this generalization is the reactivity ofa,b-unsaturated aldehydes and ketones toward nucleophiles. Even though an isolatedcarbon-carbon double bond does not react with 2 amines such as dimethylamine,3-buten-2-one reacts readily by regioselective addition.
