Correction for 'Reusable manganese compounds containing pyrazole-based ligands for olefin epoxidation reactions' by Ester Manrique et al., Dalton Trans., 2015, 44, 17529-17543.

Trideuteriated trichothecenes can be generated from diacetoxyscirpenol by a reaction sequence involving acetylation, epoxide deoxygenation, allylic oxidation, deuterium exchange, epoxidation, and reduction.

Hydrogen peroxide can be electrosynthesized from oxygen in [bmim][BF(4)]-water and used in situ for the epoxidation of alkenes.

The epoxidation of limonene with hidrogen peroxide was studied over zeolite Tibeta (a large pore material) and heteropoly acids on carbono and alumina supported. PW11/C was catalyst the best tested. Introduction In the last years, the increase in environmental restrictions lead to the search for new oxydant systems to replace the traditionals in order to avoid the generation of polluting efflue...

A family of new bio-based surfactants have been prepared via the epoxidation and PEGylation lactonic sophorolipids. This modification enhances their performance diversifying potential applications.

In a previous study, the authors showed that iron(III) [tetrakis(pentafluorophenyl)]porphyrin chloride [(F20TPP)FeCl] is catalytically inactive for cyclooctene epoxidation by hydrogen peroxide in acetonitrile but is catalytically active if the solvent contains methanol. It was suggested that the precursor to the active species is (F20TPP)Fe(OCH3) in methanol-containing solvents. The present stu...

Melatonin plays an important role in tolerance to multiple stresses in plants. Recent studies have shown that melatonin relieves photoinhibition in plants under cold stress; however, the mechanisms are not fully understood. Non-photochemical quenching (NPQ) is a key process thermally dissipating excess light energy that plants employ as a protective mechanism to prevent the over reduction of ph...

In the epoxidation of ethylene to oxide using chemical looping, Ag is supported on strontium ferrite perovskite, where acts as catalyst while perovskite an oxygen carrier. This study explores how various carriers based affect looping epoxidation. The structure carrier was varied by incorporating different ratios two phases: cubic SrFeO3, and a layered Ruddlesden-Popper (RP) phase: Sr3Fe2O7. Max...

The stability of supported metal particles is an important parameter in heterogenous catalysis. For silver catalysts on α-alumina, industrially used ethylene epoxidation, the loss surface area as result particle growth one most deactivation mechanisms. In this work, was investigated by exposing to thermal treatments. presence oxygen during heating strongly enhanced growth, and interparticle dis...
