hydrosilylation of alkenes with triethoxysilane has been achieved at 120 °C in the presence of 0.01 mol% of thioether-functionalized MCM-41 anchored rhodium complex, affording the corresponding addition products in 68–91% yields. This supported rhodium complex can be reused several times without noticeable loss of activity. Our system not only solves the basic problems of catalyst separation and recovery
