Abstract
The present invention discloses processes for producing γ-dicarbonyl compounds by contacting an aldehyde compound, an α,β-unsaturated carbonyl compound, and a catalyst composition in the presence of an amide diluent. The resultant γ-dicarbonyl compounds then can be used to synthesize pyrrole compounds, such as 2,5-dimethylpyrrole.
