Room temperature Baeyer–Villiger oxidation using molecular oxygen over mesoporous zirconium phosphate

Fabrication of Fe3O4‐l‐dopa‐CuII/SnIV@Micro‐Mesoporous‐SiO2 Catalyst Applied to Baeyer–Villiger Oxidation Reaction

“…In general, B‐V oxidations have usually been conducted by highly expensive, hazardous, shock sensitive, and environmentally malignant organic peracids as oxidants, therefore, developing greener alternatives as oxidants for B‐V reaction is a technologically crucial issue. According to many reports, two main protocols have been used for investigating greener oxidants for the B‐V reaction . One is the use of aqueous hydrogen peroxide as oxidant, this, however carries some shortcomings.…”

“…According to many reports, two main protocols have been used for investigating greener oxidants for the B-V reaction. [7] One is the use of aqueous hydrogen peroxide as oxidant, [4,[8][9][10][11] this, however carries some shortcomings. For example, hydrogen peroxidei sk inetically inert comparedt op eracids and the presence of water in the reactionm ixture leads to the hydrolysis of the product.…”

Sn-based catalysts for Baeyer-Villiger oxidations by using hydrogen peroxide as oxidant

“…Some successes have been achieved with homogeneous catalysts containing active centers based on Se [15], Re [16], Zr [17], W [18], Pd [19], Pt [20], Mn [21], or with solid acids [22,23]. All of these catalysts have at least one drawback, such as low activity or poor selectivity, tedious recovery and regeneration, or high costs for starting materials and/or safety precautions.…”

Efficient Baeyer-Villiger electro-oxidation of ketones with molecular oxygen using an activated carbon fiber electrode in ionic liquid [bmim][OTf]

“…Therefore, molecular oxygen-based protocols are powerful methods for the oxidation of ketones and attract a great attention, which make the reactions of choice in large and industrial scale applications. A number of catalytic oxidation processes based on the combination of transition metals or organocatalysts and O 2 have been developed for such a conversion [31][32][33][34]. However, these methods still suffered from environmental hazards, poor recovery of expensive metal catalysts and laborious workup procedures.…”
