N,N-Dimethylaminomethyl ferrocenium could be generated in situ and served as a terminal oxidant for Pd-catalyzed directly dehydrogenative annulations of N,N-dimethylaminomethyl ferrocene and internal alkynes. This procedure utilized the redox activity of ferrocene and avoided adding an oxidant. A series of highly arylated naphthalenes functionalized by ferrocene were obtained in 53-81% yields.

A mild aerobic intramolecular aminoacetoxylation method for the synthesis of pyrrolidine and indoline derivatives was achieved using molecular oxygen as the oxidant. A catalytic NOx species acts as an electron transfer mediator to access a high-valent palladium intermediate as the presumed active oxidant.

Introduction: The Mars Oxidant and Radical Detector is an instrument designed to characterize the reactive nature of the martian surface environment. Using Electron Paramagnetic Resonance (EPR) techniques, this instrument can detect, identify, and quantify radical species in soil samples, including those inferred to be present by the Viking experiments. This instrument is currently funded by th...

THIS ISSUE of the American Journal of Physiology-Lung Cellular and Molecular Physiology features five articles that provide new insights into the mechanisms and cellular pathways regulating oxidant signaling in lungs. Reactive oxygen species (ROS) from cellular sources have been regarded as toxic byproducts of metabolism with the potential to cause damage to lipids, proteins, and DNA (22). Oxid...

Evidences that higher natural antioxidant (NA) intake provides protection against cardiovascular disease (CVD) are contradictory. Oxidative-induced endothelial cells (ECs) injury is the key step in the onset and progression of CVD and for this reason the cellular responses resulting from NA interaction with ECs are actively investigated. This study was designed to investigate the direct impact ...

Chemical oxidants are increasingly being used for in-situ destruction of organic contaminants in ground-water. The most common implementation involves using an injection/withdrawal system to circulate oxidants (e.g., potassium permanganate, hydrogen peroxide, and Fenton’s Reagent) through a DNAPL-source zone. Since the efficiency of chemical oxidation is highly dependent on geological heterogen...
