摘要: Abstract The catalytic activity of Rh(CO)Cl(PPh2CH2CH2SiO3/22·xSiO2, (catalyst P), prepared by the polycondensation Rh(CO)Cl[PPh2CH2CH2Si(OEt)3]2 (H) with tetraethoxysilane is compared that homogeneous compound H and catalyst S, attaching to surface SiO2. In hydrosilylation 1-hexene triphenylsilane, P S exhibit similar activities. absence an olefin, effective for formation poly- oligo-siloxanes from hydrosilanes. also catalyses CO oxidation water-gas shift reaction. Qualitative trends between its physical properties are discussed.
