Oxidation of molybdenum carbonyl and related derivatives by organic halides; thermal and photochemical activation
Abstract
The thermal reaction between Mo(CO)6 and CCl4 in ethyl acetate solution at 80° involves intermediate formation of Mo(CO)5EtOAc (I), which is successively oxidised to MoI and MoV derivatives, the step Mo0→ MoI being mainly responsible for free-radical formation: (I) prepared photochemically reacts similarly with CBr4 at room temperature.
