The catalytic performance of high valent rhenium compounds is assessed in epoxidation, metathesis and dehydration reactions. The donor strength of the organic moiety is altered to identify structure-reactivity relationships. Decomposition pathways thereof are assessed to develop more stable catalysts. Beside organometallic compounds, the reactivity of rhenium heptoxide is examined. It reacts with aromatic solvents upon formation of mixed-valence Re nanoparticles. These NPs are the active species in dehydration reactions whilst the binary oxide is inactive.
