CARBONYLATION DES COMPLEXES μ-ALKYLIDENIQUES: MISE EN EVIDENCE D'UN COMPOSE MINEUR PROVENANT D'UNE DOUBLE INSERTION DE CO

While the μ-alkylidenetungsten complex, (CO)9W2CHCH=C(CH3)2 gives the expected ester resulting from CO insertion-solvolysis reactions, the μ-alkylideneiron complex (CO)8Fe2CH2 gives, as well as the expected ester, a malonate formed by double carbonylation of the bridging carbon atom.
