Abstract
Pyrrole compounds are produced by contacting a furan compound, a solid acid catalyst, and water to form a reaction mixture containing a γ-dicarbonyl compound, and then contacting the γ-dicarbonyl compound with ammonia or an ammonium salt to form a reaction product mixture containing the pyrrole compound. A representative pyrrole compound that can be synthesized using these processes is 2,5-dimethylpyrrole.
