Synthesis and characterization of SiO2-supported ruthenium complexes containing aromatic sulfonamides: as catalysts for transfer hydrogenation of acetophenone
X-ray diffraction. 4–9 were used as catalysts for the transferhydrogenation of acetophenone. 4–9 showed good catalytic activity and so the effects of the different groups were also examined. For the transferhydrogenation of acetophenone, 7–9 had similar activity to 4–6. However, the longer lifetime of 7–9 makes them more advantageous than the non-supported catalysts (4–6) in terms of catalytic cycle
