Oxidation of olefins and alcohols by peroxo-molybdenum complex derived from tris(cetylpyridinium) 12-molybdophosphate and hydrogen peroxide

Ruthenium/1,1′‐Bis(diphenylphosphino)ferrocene‐Catalysed Oppenauer Oxidation of Alcohols and Lactonisation of α,ω‐Diols using Methyl Isobutyl Ketone as Oxidant

“…[12] Ishii and coworkers used tris(cetylpyridinium) 12-molybdophosphate as catalyst and H 2 O 2 as oxidant in CHCl 3 as solvent (54% yield). [13] The same method was also used in t-BuOH (70% selectivity at 54% conversion after 24 h). [14] For a large-scale industrial process we would need selectivity to caprolactone in excess of 95%, preferably 99%.…”

Liquid-Phase Selective Oxidation by Multimetallic Active Sites of Polyoxometalate-Based Molecular Catalysts

“…The system could also be applied to epoxidations of allylic alcohols [39,66], monoterpenes [44], and a,b-unsaturated carboxylic acids [67], and to oxidations of alcohols [39,66], amines [68], and alkynes [69], as well as to oxidative transformations of diols [39]. The subsequent spectroscopic and kinetic studies on the epoxidation show that the peroxotungstate [PO 4 The V-and Mo-based heteropolyoxometalates are applicable to aerobic oxidation of hydrocarbons because of their high reduction potentials [36,37] O 40 ] 6À which is existing as thermodynamically controlled self-assembly could act as a catalyst for the selective delignification (oxidative degradation of lignin derivatives) of lignocellulose fibers [87].…”

An effective and recyclable catalytic system for alcohol oxidation in water based on a temperature-responsive catalyst

“…Polyoxometalates, as the effective catalysts for oxidation reactions with H 2 O 2 have drawn wide attention in the past years. Most procedures of alcohol oxidation with hydrogen peroxide employed polyoxometalates as catalysts [8][9][10][11][12]. However, in these catalytic systems, the use of poisonous organic solvents or the difficult recovery of the catalysts has restricted their wide applications in industrial and laboratorial synthesis.…”

“…To our best knowledge, the trilacunary silicotungstate anion of [SiW 9 O 34 ] 10-has not been reported about the catalytic activity for the oxidation of alcohols. Herein, we report the first use of this polyoxometalate anion combined with dioctadecyl dimethyl ammonium ion, [(C 18 H 37 ) 2 (CH 3 ) 2 N] 10 [SiW 9 O 34 ], to form an effective and recyclable catalyst for alcohol oxidation with hydrogen peroxide.…”

The catalyst has temperature-responsive behavior in most organic solvents during the reaction.…”
