Monolayer protected Au cluster (MPC)-bound Ru-carbene complex: synthesis and its catalytic activity in ring-closing olefin metathesis

Monolayer-protected gold cluster (Au-MPC)-bound Ru-carbene complex (MPC-7) has been synthesized and examined its catalytic activity in ring-closing olefin metathesis. The MPC-7 showed almost the same catalytic activity with that of simple molecules (Grubbs Ru-complex 1b and the thioacetate-functionalized Ru-complex 8) and reused several times.
