Bio-based green solvent for metal-free aerobic oxidation of 5-hydroxymethylfurfural to 2,5-diformylfural over nitric acid-modified starch

Metal (Cu, Au)-modified silicon nanowires for high-selectivity solvent-free hydrocarbon oxidation in air.

Metal (Au, Cu)-modified Si nanowires (SiNWs) are superior catalysts for selective oxidation of hydrocarbons, while SiNWs are a powerful substrate support (enhance efficiency and selectivity) for nanocatalysts.

p-Toluenesulfonic acid a useful and selective reagent for the oxidation of benzoins to benziles under solvent-free condition

Oxidation of some benzoins to benziles is reported by using p-toluenesulfonic acid as aselective oxidation catalyst under solvent-free condition in high yield. The adjacent carbonylgroup is necessary for the oxidation of hydroxyl group in these compounds. The reaction iscarried out in a sand-bath at 100 °C with minimum by-products.

Selective oxidation of 5-hydroxymethylfurfural to 2,5- diformylfuran over intercalated vanadium phosphate oxides

Chemoselective metal-free aerobic alcohol oxidation in lignin.

An efficient organocatalytic method for chemoselective aerobic oxidation of secondary benzylic alcohols within lignin model compounds has been identified. Extension to selective oxidation in natural lignins has also been demonstrated. The optimal catalyst system consists of 4-acetamido-TEMPO (5 mol %; TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) in combination with HNO3 and HCl (10 mol % each)...
