Li, Laiming published the artcilePreparation, characterization and evaluation of a series of heterogeneous platinum catalysts immobilized on magnetic silica with different acid ligands, Application In Synthesis of 14799-94-1, the publication is Transition Metal Chemistry (Dordrecht, Netherlands) (2019), 44(8), 779-787, database is CAplus.
Platinum was immobilized on magnetic silica gel by means of boronic, nitric, carboxylic or sulfuric acid ligands to give four heterogeneous Pt nano-catalysts, designated as Fe3O4@SiO2-BA@Pt, Fe3O4@SiO2-NA@Pt, Fe3O4@SiO2-CA@Pt and Fe3O4@SiO2-SA@Pt, resp. Particles of these mono-dispersible Pt catalysts were 10-20 nm in size and could be separated for recycling by means of a magnet. Fe3O4@SiO2-BA@Pt (0.174 mmol/g Pt) showed the best catalytic activity and selectivity, which were better than Speier’s catalyst. Its turnover numbers were up to 1.7 X 106 and 1.1 X 106 for hydrosilylation of 1-hexene or styrene, resp. This material could also catalyze the hydrosilylation of a broad range of alkenes and alkynes as substrates and methyldichlorosilane or triethoxysilane as silanes. Similar yields of 1-hexyl-methyldichlorosilane at the first and eighth runs (96.5% and 95.2%, resp.), together with a final Pt content of 0.171 mmol/g indicated the outstanding stability of Fe3O4@SiO2-BA@Pt under the catalytic reaction conditions.
