Abstract

The silica-supported tantalum hydride (≡SiO)2TaH reacts with PMe3 to form a new well-defined surface species, the trimethylphosphine disiloxy tantalum hydride (≡SiO)2TaH-(PMe3). The Ta LIII-edge EXAFS gives a first coordination sphere of ca. two oxygen atoms at 1.955 Å and one phosphorus atom at 2.615 Å. The presence of the phosphine on the metal center cancels the catalytic activity of the tantalum hydride toward metathesis of acyclic alkanes but affords the oligomerization of ethylene into 1-butene and higher oligomers.
