The synthesis of (silox)/sub 3/Ta (silox = t-Bu/sub 3/SiO/sup -/) is described. This compound exhibits characteristics which indicate that it has the ability to dissociate CO into carbides and CO/sub 2/, the initial step in the Fischer-Tropsch process.
Silox hydrides [silox = (Me3C)3SiO-] of Group 5: Do [(Me3C)3SiO]2MH2]2 (M = Nb, Ta) contain unbridged M-M bonds?

Complexes containing M-H bonds are widely recognized as being important intermediates in numerous catalytic processes. Investigations of early metal hydride reactivity have resulted in reagents useful in organic synthesis and modeling studies relevant to the Fischer-Tropsch process. A variety of group5hydrides have been described; the majority contain ancillary phosphine and/or cyclopentadienyl ligands
