DABCO-promoted photocatalytic C–H functionalization of aldehydes
Herein we present a direct application of DABCO, an inexpensive and broadly accessible organic base, as a hydrogen atom transfer (HAT) abstractor in a photocatalytic strategy for aldehyde C–H activation.

Regioselective aliphatic C–H functionalization using frustrated radical pairs
Frustrated Lewis pairs (FLPs) are well documented for the activation of small molecules such as dihydrogen and carbon dioxide^ 1 – 4 . Although canonical FLP chemistry is heterolytic in nature, recent work has shown that certain FLPs can undergo single ...

Transannular C–H Functionalization of Cycloalkane Carboxylic Acids
Cyclic organic molecules are common among natural products and pharmaceuticals^ 1 , 2 . In fact, the overwhelming majority of small-molecule pharmaceuticals contain at least one ring system, as they provide control over molecular shape, often increasing ...

C–H bond functionalization reactions enabled by photobiocatalytic cascades
Light may participate in biocatalytic processes either by direct light-induced biocatalysis or by cascading light-induced chemical reactions with biocatalytic ones, which are acknowledged as photocatalysis.

Weak Coordination as a Powerful Means for Developing Broadly Useful C–H Functionalization Reactions
Conspectus Reactions that convert carbon–hydrogen (C–H) bonds into carbon–carbon (C–C) or carbon–heteroatom (C–Y) bonds are attractive tools for organic chemists, potentially expediting the synthesis of target molecules through new disconnections in ...
