Cyclopropanes through C–H activation
Science, 2020Organic Chemistry Despite the strain inherent in triangular carbon rings, these cyclopropane motifs are surprisingly common in natural products and pharmaceuticals. Their synthesis often involves the addition of highly reactive carbenes to C=C double bonds. Clemenceau et al.

C-H activation: Good things come in threes.
Nature chemistry, 2016Three different methods that use a single ruthenium catalyst to enable the facile formation of meta- and para-substituted alkenylarenes have now been developed. The reactions proceed through a tandem alkenylation/decarboxylation process and provide several advantages over alternative approaches.

Photocatalysis in C-H Activation
1993The catalytic chemistry of organometallic complexes usually depends on coordinative unsaturation. Most substrates can only bind if an empty orbital is available on the metal to receive it. One way in which photochemistry can facilitate catalysis is to generate coordinative unsaturation by photoextrusion of a ligand. Photoextrusion of CO and H2 are both
