Thermolysis and [3+2]-Cycloaddition Reactions of 2,3-Diferrocenyl- and 2,3,-Diruthenocenylcyclopropenones
2,3-Diferrocenyl- and 2,3-diruthenocenylcyclopropenone undergo thermolysis at ∼180°C with opening of the small ring via ketenocarbenes. Intramolecular transformation of the latter occurs with elimination of CO to yield dimetallocenylacetylenes. Alternatively, they enter into 1,3-dipolar cycloaddition reactions with C≡C or C=C multiple bonds to give cyclopentadienone or cyclopentenone derivatives, respectively.
