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 …

We present here a review of the photochemical and electrochemical applications of multi-
site proton-coupled electron transfer (MS-PCET) in organic synthesis. MS-PCETs are redox …

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 …

Hydrogen atom transfer (HAT), a key step in many chemical, environmental, and biological
processes, is one of the fundamental chemical reactions: A− H+ B→ A+ H− B. Traditional …

The first highly enantioselective catalytic protocol for the reductive coupling of ketones and
hydrazones is reported. These reactions proceed through neutral ketyl radical intermediates …

An enantioselective, radical-based method for the intramolecular hydroamination of alkenes
with sulfonamides is reported. These reactions are proposed to proceed via N-centered …

Noncovalent interactions (NCIs) are critical elements of molecular recognition in a wide
variety of chemical contexts. While NCIs have been studied extensively for closed-shell …

Efficient interfacial electrocatalysis requires rapid concerted proton–electron transfer (CPET)
at the electrode surface, a process for which there is little mechanistic understanding. In …

The proton-coupled electron transfer (PCET) reaction has drawn extensive attention for its
widespread occurrence in chemistry, biology, and materials science. The mechanistic …

Here we present a detailed kinetic study of the multisite proton-coupled electron transfer (MS-
PCET) activations of aryl ketones using a variety of Brønsted acids and excited-state Ir (III) …
