Copper Catalyzed C−H Activation

The Chemical Record, 2018
AbstractActivation of C−H bonds and their application in cross coupling chemistry has received a wider interest in recent years. The conventional strategy in cross coupling reaction involves the pre‐functionalization step of coupling reactants such as organic halides, pseudo‐halides and organometallic reagents.

C–H activation

Current Opinion in Chemical Biology, 1999
Although the biocatalytic activation of carbon-hydrogen bonds by oxidation to alcohols was one of the first biotransformations to be exploited by the chemical industry, this remarkable process continues to be the subject of intense research activity.

C–H activation

2014
The C–H activation reaction is a reaction that cleaves a carbon–hydrogen bond. Here the carbon–hydrogen bond is mostly referred to unactivated carbon–hydrogen bonds.

Electrophilic C−H Activation at {Cp*Ir}:  Ancillary-Ligand Control of the Mechanism of C−H Activation

Journal of the American Chemical Society, 2006
Density functional calculations on the low-temperature cyclometalation of dimethylbenzylamine with [IrCl2Cp*]2/NaOAc have characterized a novel electrophilic activation pathway for C-H bond activation. C-H activation occurs from [Ir(DMBA-H)(kappa2-OAc)Cp*]+, and OAc plays a central role in determining the barrier for reaction.

Concise Synthesis of Polysubstituted Carbohelicenes by a C−H Activation/Radical Reaction/C−H Activation Sequence

Angewandte Chemie, 2018
AbstractDisclosed herein is the merging of C−H activation and radical chemistry, enabling rapid access to a structurally diverse family of fused carbohelicenes through the fusion of α‐acetylnaphthalenes with alkynes under oxidative conditions. This cascade process exhibits exquisite chemoselectivity and regioselectivity.

Intramolecular C−H Activation Reactions of Molybdenacyclobutanes

Journal of the American Chemical Society, 2006
Molybdenacyclobutane complexes can be prepared by reaction of Cp*Mo(NO)(=CHCMe3) (formed spontaneously by loss of neopentane from Cp*Mo(NO)(CH2CMe3)2 (1) under ambient conditions) with cyclic olefins, including cyclopentene, cycloheptene, and cyclooctene. The cyclopentene metallacyclobutane orients the metallacycle bridgehead protons cis to each other.
