Abstract Cyclohexa-2, 4-dienones stabilized by coordination to tricarbonyliron are obtained when the tosylhydrazones of tricarbonyliron-complexed α-dienones are thermolyzed in the presence of strong bases. This cyclocarbonylation reaction of carbenic intermediates is fairly general and can be used to synthesize various mono and polycyclic cyclohexadienone complexes or their decomplexed phenolic tautomers, and among them a new salicylate in ...
