AbstractTo obtain stable derivatives of α‐unsubstituted pyrroles, the reaction of the test pyrrole9with a series of chalcones14a–hwere studied.Michaeladducts16b–hcould be isolated. In order to synthesize coloured derivatives, the reaction of different pyrroles9, 21, 23, and25with diphenylpropynone19was investigated. In these cases, too,Michael‐addition products were formed. The intense absorption band around 400 nm makes the identification of these derivati
