This review provides a systematic overview of radical-mediated C–O bond cleavage of alcohols in photocatalysis, detailing radical generation mechanisms and transformation pathways across diverse reactions.
In this tutorial, reaction scopes, limitations and mechanisms of radical acylations are summarized and discussed according to reaction types and catalytic systems.
By harnessing the reactivity of alkynes and alkenes under photochemical conditions, novel pathways have been unlocked to construct N-heterocyclic compounds, allowing for more efficient and sustainable synthesis.
This feature article presents all the recent reports on photoredox-catalyzed redox-neutral carbon–heteroatom coupling reactions up to March 2023.
Recent years have witnessed the emergence of direct intermolecular C(sp3)–H bond functionalization using in situ generated aryl/alkyl radicals as a unique class of hydrogen atom transfer (HAT) agents.
