Sulfonated carbon catalyzed oxidation of aldehydes to carboxylic acids by hydrogen peroxide

New heterogeneous catalyst for the esterification of fatty acid produced by surface aromatization/sulfonation of oilseed cake

“…e l s e v i e r . c o m / l o c a t e / f u e l [38], bean vermicelli [39], de-oiled canola [40], polymers [41], D-glucose and sulfonated ordered mesoporous carbons [42][43][44][45][46]. These catalysts have shown great potential to replace the traditional homogeneous H 2 SO 4 catalysis.…”

Na4PMo11VO40-catalyzed one-pot oxidative esterification of benzaldehyde with hydrogen peroxide

“…[15][16][17][18] Solid-supported catalysts have been demonstrated to be active in the oxidation of aldehydes with hydrogen peroxide. [19][20][21][22][23] Thakur et al investigated oxidation with hydrogen peroxide of aromatic and aliphatic aldehydes to methyl esters over a VO(acac) 2 /TiO 2 catalyst. 24 In this sense, vanadium catalysts have been highlighted as effective catalysts in several oxidation reactions, mainly when used in Keggin heteropoly compounds.…”

Mechanistic investigations on Pinnick oxidation: a density functional theory study

“…The oxidation of aldehydes to carboxylic acids is a fundamental transformation in organic chemistry that is applied in many syntheses (examples of the use of Pinnick oxidation in synthesis of some bioactive molecules [1][2][3][4][5], Pinnick-type protocol for amidation of aldehyde [6]). Despite the variety of reagents available to achieve this oxidation (for general transformation of aldehyde into carboxylic acid, see [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]), few of them are suitable for a broad range of aldehydes and/or tolerate a wide range of functional groups [22,23]. Beside selectivity problems, high costs and complexity of the reaction conditions made the application of this transformation on a large scale reasonably difficult.…”
