Selective oxidation of alcohol over supported gold catalysts: methyl glycolate formation from ethylene glycol and methanol

Aerobic Oxidation of Alcohols over Gold Catalysts: Role of Acid and Base

“…Following the discovery by Haruta et al, a variety of aerobic oxidation reactions have been reported [7,8]. For instance, gold nanoparticles were used in the oxidation of alcohols to aldehydes [9], carboxylic acids [10][11][12][13][14] or esters [15,16], in the oxidation of aldehydes to esters [17] or acids [18] in epoxidations of olefins [19,20], and in the oxidation of amines to amides [21]. Although Haruta et al [6] were able to achieve low temperature aerobic oxidation of carbon monoxide, most aerobic oxidations using gold catalysts require temperatures and oxygen pressures well above ambient conditions.…”

Reaction mechanism for methanol oxidation on Au(111): A density functional theory study

“…During the past two decades, numerous efforts have been devoted to developing the catalytic activity of gold for different purposes, for instance, the use of fuel cells [2], synthesis of esters, olefin epoxidation [3][4][5][6][7][8], and selective oxidation of alcohols [9][10][11][12][13][14][15][16][17][18][19][20]. Among them, alcohol oxidation is of particular interest since it is not only one of the most important reactions in industry and organic synthesis, but also one that Au-based catalysts carry out most efficiently.…”

Chemicals from Renewables: Aerobic Oxidation of Furfural and Hydroxymethylfurfural over Gold Catalysts

“…In the aerobic oxidations performed at room temperature, no oxidation of methanol is observed at all. At higher temperatures and at longer reaction times some methanol can be oxidized to carbon dioxide or formates (up to 0.4 mol per mole of substrate), [30] and thus it is important to optimize the reaction time.…”
