Enolates of carbonyl compounds having a methine α-carbon undergo 2-nitro-1-alkenylation (nitroolefination) to form quarternary C-atom next to the carbonyl group on reaction with β-nitroenamines via an addition elimination process. The geometry of the resulting nitroolefins proved to be of the E type.
