Benefits and limitations of using Fe(III)-EDDS for the treatment of highly contaminated water at near-neutral pH

This study evaluates the use of the Fe(III)-EDDS complexing agent as an alternative to conventional acidic pH photo-Fenton for the treatment of the pesticide imidacloprid in natural water. The main objective is to estimate whether Fe(III)-EDDS is a viable ...

NO binding kinetics in myoglobin investigated by picosecond Fe K-edge absorption spectroscopy

Majed Chergui, Thomas James Penfold, Camelia Borca, Marco Eli Reinhard, Frederico Alves Lima, Mercedes Hannelore Rittmann-Frank, Jochen Rittmann, Mahsa Silatani

Diatomic ligands in hemoproteins and the way they bind to the active center are central to the protein's function. Using picosecond Fe K-edge X-ray absorption spectroscopy, we probe the NO-heme recombination kinetics with direct sensitivity to the Fe-NO bi ...

Synthetic chemistry with nitrous oxide

Kay Severin

This review article summarizes efforts to use nitrous oxide (N2O, ‘laughing gas’) as a reagent in synthetic chemistry. The focus will be on reactions which are carried out in homogeneous solution under (relatively) mild conditions. First, the utilization o ...

Identifying the major intermediate species by combining time-resolved X-ray solution scattering and X-ray absorption spectroscopy

Thomas James Penfold

Identifying the intermediate species along a reaction pathway is a first step towards a complete understanding of the reaction mechanism, but often this task is not trivial. There has been a strong on-going debate: which of the three intermediates, the CHI ...

Novel FeOx–polyethylene transparent films: synthesis and mechanism of surface regeneration

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

The first evidence for the synthesis of a uniform, adhesive polyethylene–FeOx (PE–FeOx) surface leading efficiently to bacterial inactivation is addressed in this study. PE was loaded with 0.04–0.08% Fe wt/wt PE after RF-plasma pretreatment was required to ...

A Mechanochemical Switch to Control Radical Intermediates

Ursula Röthlisberger, Elizabeth Claire Brunk

B-12-dependent enzymes employ radical species with exceptional prowess to catalyze some of the most chemically challenging, thermodynamically unfavorable reactions. However, dealing with highly reactive intermediates is an extremely demanding task, requiri ...

Synthesis of Multifunctionalized 1,2,3,4-Tetrahydropyridines, 2,3-Dihydropyridin-4(1H)-ones, and Pyridines from Tandem Reactions Initiated by [5+1] Cycloaddition of N-Formylmethyl-Substituted Enamides to Isocyanides: Mechanistic Insight and Synthetic Application

Jieping Zhu

Tandem reactions for the efficient synthesis of multifunctionalized 1,2,3,4-tetrahydropyridines, 2,3-dihydropyridin-4(1H)-ones, and pyridine derivatives have been developed and reaction mechanisms have been investigated. Synthetic cascades are initiated by ...
