Abstract

Propane metathesis reactions over group 2–5 metal hydrides were investigated. Among the tested metal hydrides, TiH₂ exhibited the highest butane yield as a metathesis reaction product. Fully-hydrogenated TiH₂ is much more active than dehydrogenated TiH and Ti metal. Surface low-valent Ti species over TiH₂ is involved in the propane metathesis reaction. This study is the first example of carbon–carbon bond cleavage and catalytic formation over bulk metal hydrides.
