A series of pyrroles were synthesized from primary amine (including fatty amine and aromatic amine) and acetonyl-acetone through a Paal-Knorr reaction catalyzed by formic acid at room temperature under solvent-free conditions. The advantages of this method are the mild reaction conditions, simple procedure, rapidity, easy separation of products, good yields and environmental friendliness.

Key words: formic acid, Paal-Knorr reaction, room temperature, pyrrole, solvent-free reaction
