During the past 12 months work has continued on the cleavage of carbon monoxide by W{sub 4}(OCH{sub 2}R){sub 12} compounds. This reaction occurs under extremely mild conditions in hydrocarbon solvents. We have initiated a study of the reactivity of the hydride ligand in the compounds W{sub 2}({mu}-H)(O-cyclo-pentyl){sub 7}L where L = a substitutionally labile ligand. We know that it reacts with a variety of unsaturated molecules including ethylene, allene, acetylene, nitriles, ketones, carbon monoxide and carbon dioxide. The products and the details of these reactions are under investigation. In a new initiative we have started to look at the chemistry of some siloxide supported Mo and W clusters. The simple dinuclear siloxide W{sub 2}(OSiBu{sup t}Me{sub 2}){sub 6} (M {equivalent to} M) shows a remarkable rich chemistry and one that is surprisingly different from the structurally related W{sub 2}(OR){sub 6} compounds.
