The metathesis of ethane and propane catalysed by tantalum hydride supported on silica or MCM-41 was studied under static and dynamic conditions. During the reaction, the rate decreased over time, indicating deactivation of the catalyst. The evolutio

Only 50% of the silica-supported tantalum hydride sites are active in the metathesis of propane. Indeed, more than 45% of the tantalum hydride can be eliminated by a selective oxygen poisoning of inactive sites with no significant decrease in the glo

The silica-supported tantalum hydride, (⋮SiO)2Ta(III)H, is transformed under hydrogen by thermal treatment up to 500 °C into a new well-defined surface species, the trisiloxy tantalum (⋮SiO)3Ta(III). The Ta LIII-edge EXAFS gives a first coordina

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 o

The modification of a mesoporous silica surface with Si(Ind)(CH3)2Cl and the immobilization of CpZr(NMe2)3 on this surface was studied via IR-spectroscopy. To reduce side reactions, the indenyl-modified silica was reacted with hexamethyldisilazane (H

Silica-supported tantalum and tungsten hydrides present unusual properties in the activation of alkanes. They activate the C H bonds of cycloalkanes to form the corresponding surface metal–cycloalkyl complexes. They catalyse the metathesis reaction

The Ta(CHtBu)(CH2tBu)3 complex 1 reacts with the OH groups of a MCM-41 mesoporous silica dehydroxylated at 500 °C to form the monosiloxy surface species [(⋮SiO)Ta(CHtBu)(CH2tBu)2] 2, with evolution...

Alkane metathesis, a reaction catalyzed by the silica-supported tantalum hydride [(SiO)2Ta-H], 1, which transforms acyclic alkanes into their higher and lower homologues, was reported in 1997. New studies conducted in a continuous flow reactor in the

Heterogeneous catalysts are widely used in industrial applications; they are often easily prepared at a low cost and can be conveniently separated from the reaction medium. However it is always difficult to define and control the active site and then
