ABSTRACT:

Following studies of the reactions of dimolybdenum hexaalyoxides with alkynes, nitriles, and carbon monoxide, great differences were found using tungsten analogues, reflecting tungsten's greater reducing power.  The tungsten reactions provide the first homogeneous examples of the splitting of C triple bond O to carbide and oxide, and provide a model for heterogeneous catalytic processes believed to be the first and most critical step in Fischer-Tropsch chemistry. The chemical reactivity of carbido tungsten clusters is being studied. A series of mixed metal alkoxides of molybdenum and tungsten were prepared by alcoholysis reactions. (ERA citation 08:036618)
