Tandem C–O and C–H Activation at Palladium Enables Catalytic Direct C–H Alkenylation with Enol Pivalates [PDF]
The use of oxygen-based electrophiles in cross-coupling remains challenging for substrates with strong C–O bonds, with few examples that can combine C–O activation with an-other strong-bond activation in tandem.

Undirected C-H Bond Activation in Aluminium Hydrido Enaminonates
Two new aluminium hydrido complexes were synthesized by reacting AlH3 with the enaminone ligand N-(4,4,4-trifluorobut-1-en-3-on)-6,6,6-trifluoroethylamine (HTFB-TFEA) in different molar ratios to obtain mono- and di-hydrido-aluminium enaminonates.

Divergent isoindolinone synthesis through palladium-catalyzed isocyanide bridging C–H activation
Summary: The formation of thermodynamically accessible metallacycle is crucial to achieve site-selective C–H bond activation. Here, we report an isocyanide-bridging C–H activation through the formation of a five-membered palladacycle. As such, a proximal
