Heterometallic carbonyl cluster oxide. Formation, structure and reactivity of WRe2 oxo-acetylide cluster compounds
Abstract
Cluster [WRe2(C5Me5)(O)(CO)8(CCPh)]1a possessing a terminal oxo ligand is prepared by treatment of the acetylide cluster [WRe2(C5Me5)(CO)9(CCPh)] with O2 or N2O; hydrogenation of 1a affords three isolable clusters, showing an example of oxo-ligand mediated sequential conversion of acetylide to alkenyl and alkylidene.
