In situ generated gold nanoparticles inside the nanospaces of periodic mesoporous organosilica with an imidazolium framework (Au@PMO-IL) were found to be highly active, selective, and reusable catalysts for the aerobic oxidation of activated and nonactivated alcs. under mild reaction conditions. The catalyst was characterized by nitrogen adsorption-desorption measurement, thermogravimetric anal. (TGA), transmission electron microscopy (TEM), elemental anal. (EA), diffuse reflectance IR Fourier transform spectroscopy (DRIFT), XPS, and inductively coupled plasma at. emission spectroscopy (ICP-AES). The catalyst exhibited excellent catalytic activity in the presence of either Cs2CO3 (35°) or K2CO3 (60°) as reaction bases in toluene as a reaction solvent. Under both reaction conditions, various types of alcs. (up to 35 examples) including activated benzylic, primary and secondary aliphatic, heterocyclic, and challenging cyclic aliphatic alcs. converted to the expected carbonyl compounds in good to excellent yields and selectivity. The catalyst was also recovered and reused for at least seven reaction cycles. Data from three independent leaching tests indicated that amounts of leached gold particles were negligible (<0.2 ppm). It is believed that the combination of bridged imidazolium groups and confined nanospaces of PMO-IL might be a major reason explaining the remarkable stabilization and homogeneous distribution of in situ generated gold nanoparticles, thus resulting in the highly active and recyclable catalyst system.3-Pyridinemethanol(cas: 100-55-0Safety of 3-Pyridinemethanol) was used in this study.
3-Pyridinemethanol(cas: 100-55-0) belongs to pyridine. Pyridine is widely used in the precursor to agrochemicals and pharmaceuticals. Also, it is used as an important reagent and organic solvent.Safety of 3-Pyridinemethanol
