ROLE OF Mn(TPP)Cl IN THE EPOXIDATION WITH SINGLET OXYGEN [PDF]
Journal of Sciences, Islamic Republic of Iran, 2000 Mn(TPP)Cl catalyzes cooxidation of olefin in the singlet oxygenation of sulfid. Mn(TPP)Cl is able to transfer an oxygen atom from a peroxidic intermediate generated in singlet oxygenation of sulfide to a metal ion affording metal 0x0 species which is ...

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 ...

Carbon Energy, EarlyView.A combination of visible light and thermal energy accelerates the CO formation rate up to 57 times compared to dark conditions using a 3Cu/CeTiO2−x catalyst. Kinetic analysis, as well as steady state and transient spectroscopy, was applied under photocatalytic conditions to analyze and disentangle the reaction channels under dark and illuminated ...

Chemistry – A European Journal, EarlyView.The development of chemoselective catalysts that operate across structurally diverse substrates remains a long‐standing challenge. Here, we demonstrate that a random heteropolymer bearing carboxylic acid and urea residues functions as a general epoxidation catalyst for olefinic quaternary ammonium salts.

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 ...

Assessing Benzene Dimer Interactions in Solution With a Molecular Balance
Chemistry – A European Journal, EarlyView.The Gecko in the ToC was generated with Canva (31.03.2025 11:00 pm), the remaining graphics by the authors. ABSTRACT We present a combined experimental and computational study of a 1,4/1,6‐dibenzyl substituted cyclooctatetraene (COT)‐based molecular balance as a model to assess the benzene dimer interactions in solution.
