Abstract

original image

Surface does matter: Lewis acidic Al and Lewis basic O atoms of γ-Al2O3 interact through multiple strong interactions with adsorbed methyltrioxorhenium. The major species, which coordinates through oxo ligands, readily adopts an octahedral geometry, whereas the minor μ2-CH2 species prefers a lesser degree of coordination, which is in line with its reactivity in alkene metathesis.
