We present an update and revision to our 2010 review on the topic of proton-coupled
electron transfer (PCET) reagent thermochemistry. Over the past decade, the data and …

Nitroxides, also known as nitroxyl radicals, are long-lived or stable radicals with the general
structure R1R2N–O•. The spin distribution over the nitroxide N and O atoms contributes to …

The most fundamental concepts in chemistry are structure, energetics, reactivity and their
inter-relationships, which are indispensable for promoting chemistry into a rational science …

Superoxide, O2•−, is formed in all living organisms that come in contact with air, and,
depending upon its biological context, it may act as a signaling agent, a toxic species, or a …

Many, if not most, redox reactions are coupled to proton transfers. This includes most
common sources of chemical potential energy, from the bioenergetic processes that power …

Understanding the energy it takes to build or break chemical bonds is essential for scientists
and engineers in a wide range of innovative fields, including catalysis, nanomaterials …

Superoxide dismutases (SODs) catalyze the de toxification of superoxide. SODs therefore
acquired great importance as O2 became prevalent following the evolution of oxygenic …

There have been significant advances in our understanding of mononuclear nonheme iron
oxygenases since our 1996 Chemical Reviews article, 1 promoted in large part by the many …

This Review describes the application of nitroxides to synthesis and polymer chemistry. The
synthesis and physical properties of nitroxides are discussed first. The largest section …

In an era dominated by the utilization of hydrocarbon mixtures (ie, oil and natural gas) as
feedstocks for the chemical industry, the functionalization of CH bonds, particularly in a …
