N2 - Surface organometallic chemistry: Similar electronic properties of molecular and surface siloxy ligands in 1 m and 1 were revealed by a structural investigation with solid-state NMR spectroscopy and a reactivity study in olefin metathesis. Despite similar initial turnover frequencies, the silica-supported catalyst 1 is more stable than 1 m and allows it to achieve higher turnovers, thus showing the advantage of site isolation on surfaces. (Figure Presented)
