Metallocene analogues of chalcones with a metallocene (ferrocene, ruthenocene, cymantrene) bound to the β-carbon atom of the multiple bond, or to the carbonyl group were prepared. The double bond of ferrocene and ruthenocene analogues of chalcones was acetylated when the metallocene was bound to the β-carbon atom of the double bond. No similar double bond acetylation was observed with cymantrene or N-methylpyrrole analogues of chalcones.
