Enantioselective epoxidation of non-functionalised alkenes using a urea–hydrogen peroxide oxidant and a dimeric homochiral Mn(III)-Schiff base complex catalyst

Adsorption of hydrogen peroxide on functionalized mesoporous silica surfaces

“…It is reasonably stable, readily available, inexpensive, and generates only water as a by-product [5]. Although its molecule is similar to water, it has not been much studied in a pure state because of its instability.…”

Light driven styrene epoxidation and hydrogen generation using H2O as an oxygen source in a photoelectrosynthesis cell

“…In this respect, there is a strong need for the development of new epoxidation methods that make use of safer oxidants and minimize waste products. The employment of hydrogen peroxide is an attractive option both on environmental and economic grounds [4][5][6][7] giving just water as a byproduct. Another option is to use water as the source of oxygen for the epoxidation reaction with the formation of hydrogen as a valuable side product as indicated in the equation below, 8 which involves the input of 37.35 Kcal mol -1 given its uphill thermodynamics that can be provided thermically 9,10 or photochemically 11 with sunlight.…”

Structural Elucidation of Transition Metal Complexes of the Schiff Base of 5-Nitro Salicylaldehyde and Anthranalic Acid Using ¹H NMR, Thermal Analysis, Diffused Reflectance and ESR Data

“…Schiff base and their metal complexes have been used as a synthetic model for the metal containing sites metallo -protein and enzymes [2][3]. The Schiff base and their transition metal complexes are used as a catalyst for the number of catalytic process such as oxidation, epoxidation and polymerization of alkene [4][5][6]. Schiff base of 5 nitro salicylaldehyde, anthranalic acid and its metal complexes of Co(II),Ni(II),Cu(II) and Zn(II) with their characterization by using elemental analysis , UV-Visible, IR, X-Ray diffraction were already reported by this lab [7] In this paper we are reporting further investigation of the Schiff base and its metal complexes by using 1 H-NMR ,TGA, Diffused reflectance and ESR spectroscopy.…”
