The addition of halogenocarbons to alkenes in the presence of (I) has been the subject of a detailed kinetic study.These results, together with the results of cross-over addition reactions of a halogenocarbon mixture and cross-over studies on catalyst mixtures of (I) and (IV) are interpreted in favour of a mechanism involving catalysis by an intact binuclear complex, but which also involves free radical intermediates.Studies on catalysis by (II) additional to those we reported earlier, suggest an analogous mechanism in this case, but also involving CO dissociation from the hexacarbonyl yielding IV as the active catalyst.A preliminary study of catalysis by <2CH2> (III) suggests this complex also follows a similar mechanism.
