Hydrogenation and degradation of carbon disulfide by organometallic cluster hydride complexes. Reaction of carbon disulfide with (. mu. -H)/sub 2/Os/sub 3/(CO)/sub 9/(P(CH/sub 3/)/sub 2/C/sub 6/H/sub 5/)
Hydrogenation and Degradation of Carbon Disulfide by Organometallic Cluster Hydride Complexes. Reaction of Carbon Disulfide with (..mu..-H)/sub 2/Os/sub 3/(CO)/sub 9/ (P(CH/sub 3/)/sub 2/ C/sub 6/H/sub 5/). The ability of triosmium-hydride cluster complexes to effect the hydrogenation of small molecule was examined, and it was found that (..mu..-H)/sub 2/ Os/sub 3/ (CO)/sub 10/ reacts with CS/sub 2/ via an unusual dicluster reaction to produce the molecule (..mu..-S/sub 2/ CH/sub 2/) (..mu..-H) Os/sub 3/ (CO)/sub 10/)/sub 2/. Each cluster has transferred one hydrogen atom to the carbon atom of the CS/sub 2/ molecule and produced a dithiomethylene ligand which then links the two cluster units. The reaction of (..mu..-H)/sub 2/ Os/sub 3/ (CO)/sub 9/ (P(CH/sub 3/)/sub 2/ C/sub 6/H/sub 5/) with CS/sub 2/ was examined. An entirely new reaction was found in which a single cluster complex reacts with one molecule of CS/sub 2/, transfer both its hydrogen atoms to the carbon atom, cleaves a single sulfur atom from the original CS/sub 2/ unit, and ultimately produces a fractured cluster complex containing inorganic sulfide and a bridging thioformaldehyde ligand. Cluster compounds do possess remarkable abilities to hydrogenate and fragment small substrate molecules like CS/sub 2/. (2 figures)
