Au/SiO2 as a highly active catalyst for the selective oxidation of silanes to silanols.
Au/SiO(2), which was prepared properly to have a high dispersion of gold nanoparticles, acts as an extremely active catalyst for the selective oxidation of a variety of silanes. It outperforms other reducible oxide supported gold catalysts thanks to the affinity of the silica support to the silane substrate.
متن کاملSupported gold nanoparticle catalyst for the selective oxidation of silanes to silanols in water.
Hydroxyapatite-supported gold nanoparticles (AuHAP) can act as highly efficient and reusable catalysts for the oxidation of diverse silanes into silanols in water; this is the first catalytic methodology for the selective synthesis of aliphatic silanols using water under organic-solvent-free conditions.
متن کاملSelective Oxidation of Xylenes to Toluic Acids
A mixture of manganese, cobalt and lead para-amino benzoates supported on silica gel is used to catalyze oxidation of xylenes to toluic acids in presence of oxygen or air. Reactions are clean and catalysts can be recovered easily and reused.
متن کاملOxidation of tertiary silanes by osmium tetroxide.
In the presence of an excess of pyridine ligand L, osmium tetroxide oxidizes tertiary silanes (Et(3)SiH, (i)Pr(3)SiH, Ph(3)SiH, or PhMe(2)SiH) to the corresponding silanols. With L = 4-tert-butylpyridine ((t)Bupy), OsO(4)((t)Bupy) oxidizes Et(3)SiH and PhMe(2)SiH to yield 100 +/- 2% of silanol and the structurally characterized osmium(VI) mu-oxo dimer [OsO(2)((t)Bupy)(2)](2)(mu-O)(2) (1a). With...
