A.S. is grateful to BASF for a graduate fellowship, and the other authors would also like to thank BASF, the CNRS, and the ESCPE (Lyon) for financial support. We also thank Drs. V. Böhm, M. Röper, and D. Schneider for helpful discussions.
Graphical Abstract
Supported metathesis: Grafting (CH3)ReO3 onto alumina covered with surface trimethylsilyl groups increases the efficiency and selectivity of this catalyst in olefin metathesis (see scheme). The SiMe3 groups (X) modify the adsorption properties of alumina by favoring desorption and thereby disfavoring secondary reactions.
