Chemoenzymatic Epoxidation of Alkenes and Reusability Study of the Phenylacetic Acid
The Scientific World Journal, 2014 Here, we focused on a simple enzymatic epoxidation of alkenes using lipase and phenylacetic acid. The immobilised Candida antarctica lipase B, Novozym 435 was used to catalyse the formation of peroxy acid instantly from hydrogen peroxide (H2O2) and ...

European Journal of Inorganic Chemistry, EarlyView.The correlation between the structures of metal complexes immobilized in the mesopores of hydrophobically modified silicate supports was examined in relation to the catalytic activities toward C‐H oxidation. On the alkene oxidation with H2O2, the iron catalyst bearing bis(imidazolyl)methane ligand promotes allylic oxidation, whereas the mononuclear ...

Lipase-mediated epoxidation of alkenes in supercritical carbon dioxide
Green Chemistry Letters and Reviews, 2018 In this work, supercritical carbon dioxide was used as reaction media in the lipase-mediated epoxidation of alkenes for the first time. Under the optimal conditions (alkene (1 mmol), novozym 435 (15 mg), H2O2 (50% aqueous solution, 1.4 mmol), n-caprylic ...
