Direct photocatalyzed hydrogen atom transfer (d-HAT) can be considered a method of
choice for the elaboration of aliphatic C–H bonds. In this manifold, a photocatalyst (PCHAT) …

Alkyl radicals are key intermediates in organic synthesis. Their classic generation from alkyl
halides has a severe drawback due to the employment of toxic tin hydrides to the point that …

Radical–radical couplings are mostly nearly diffusion‐controlled processes. Therefore, the
selective cross‐coupling of two different radicals is challenging and not a synthetically …

Research and industrial interest in radical C–H activation/radical cross-coupling chemistry
has continuously grown over the past few decades. These reactions offer fascinating and …

The development of a mild, atom-and step-economical catalytic strategy that effectively
generates value-added molecules directly from readily available commodity chemicals is a …

The selective functionalization of alkanes has long been recognized as a prominent
challenge and an arduous task in organic synthesis. Hydrogen atom transfer (HAT) …

The present review offers an overview of the current approaches for the photochemical and
photocatalytic generation of reactive intermediates and their application in the formation of …

The synergistic control of the SH2 transition states of hydrogen abstraction by polar and
steric effects provides a promising strategy in achieving site-selective C (sp3)–H …

Despite their abundance in organic molecules, considerable limitations still exist in synthetic
methods that target the direct C− H functionalization at sp3‐hybridized carbon atoms. This is …

Polyoxometalates (POMs), which are anionic metal oxide clusters, have recently attracted
considerable attention as photocatalysts because of their unique photoinduced charge …
