    • This catalyst precursor should release the two ethylene ligands upon rapid hydrosilylation prior to entering a catalytic cycle
    • The reaction of 1a with [RhCl(C2H4) 2]2 should form [silica gel 60N]-SMAP-RhCl(C 2H4)2, a can also be used as equally active catalyst precursor but it needs to be aged with a hydrosilane before the addition of a ketone
    • 2. This catalyst precursor should release the two ethylene ligands upon rapid hydrosilylation prior to entering a catalytic cycle. Preformed, well-defined complex 6a can also be used as equally active catalyst precursor but it needs to be aged with a hydrosilane before the addition of a ketone.
