Towards mild metal-catalyzed C–H bond activation

Chemical Society Reviews, 2011
Functionalizing traditionally inert carbon-hydrogen bonds represents a powerful transformation in organic synthesis, providing new entries to valuable structural motifs and improving the overall synthetic efficiency. C-H bond activation, however, often necessitates harsh reaction conditions that result in functional group incompatibilities and limited ...

Graphene-based Photonic C-H bond activation

Frontiers in Optics + Laser Science 2021, 2021
C-H bond activation is critical for the realization of photosynthesis. We present a graphene-based spectroscopic technique (J. Phys. Chem. C 2021, 125, 7, 3811) [1] that controls the C-H bond Raman modes allowing for the study of thermodynamic changes at the molecular level.

Iridium‐Catalyzed Hydroarylation via C−H Bond Activation

The Chemical Record, 2021
AbstractHydroarylation reactions via C−H activation, which compensate for shortcomings of classical methods based on the Friedel‐Crafts reaction, is one of the most attractive methods to synthesize substituted arenes. This Personal Account reviews our recent studies on iridium‐catalyzed intermolecular hydroarylation of vinyl ethers, alkynes ...

CH Bond Activation by f‐Block Complexes

Angewandte Chemie International Edition, 2014
AbstractMost homogeneous catalysis relies on the design of metal complexes to trap and convert substrates or small molecules to value‐added products. Organometallic lanthanide compounds first gave a tantalizing glimpse of their potential for catalytic CH bond transformations with the selective cleavage of one CH bond in methane by bis ...

Oxygen‐Promoted CH Bond Activation at Palladium

Angewandte Chemie International Edition, 2014
Abstract[Pd(P(Ar)(tBu)2)2] (1, Ar=naphthyl) reacts with molecular oxygen to form PdII hydroxide dimers in which the naphthyl ring is cyclometalated and one equivalent of phosphine per palladium atom is released. This reaction involves the cleavage of both CH and OO bonds, two transformations central to catalytic aerobic oxidizations of hydrocarbons ...

Real-world C-H bond activation

Chemical & Engineering News Archive, 1997
Details of a mechanism for activating the normally inert carbon-hydrogen bond in room-temperature alkane solution have emerged from experiments using ultrafast infrared spectroscopic techniques. C-H bond activation is potentially useful for converting alkanes into functionalized organic molecules.

Rhodium-Catalyzed C–H Bond Functionalization with Amides by Double C–H/C–N Bond Activation

Organic Letters, 2016
The first C-H bond functionalization with amides as the coupling partners via selective activation of the amide N-C bond using rhodium(I) catalysts under highly chemoselective conditions is reported. Notably, this report constitutes the first catalytic activation of the amide N-C(O) bond by rhodium.
