Dicarbonyl compounds 2 carrying a phosphonate group were obtained by utilizing a dually N-heterocyclic carbene (NHC) catalyzed dominoreaction involving the intramolecular hydroacylation of salicylalkynylphosphonates 1 and a subsequent intermolecular Stetterreaction with aromaticaldehyde at room temperature. In addition, 2 can also be applied for the synthesis of benzopyranopyrrole carrying a phosphonate
