Photo-Electrochemical C-H Bond Activation of Cyclohexane Using a WO3 Photoanode and Visible Light.

Angewandte Chemie, 2018
The photo-electrochemical C-H bond activation of cyclohexane to produce cyclohexanol and cyclohexanone (KA oil) with high partial oxidation selectivity (99 %) and high current utilization ratio (76 %) was achieved in air at room temperature at ...

Palladium-Catalyzed Site-Selective [3+2] Annulation via Benzylic and meta C-H Bond Activation.

Angewandte Chemie, 2020
The palladium-catalyzed [3+2] annulation of aromatic amides with maleimides via the activation of ortho benzylic C-H and meta C-H bonds is reported. Carboxamide and anilide type substrates that contain a 2-methylthiophenyl group both participate in this [

C-H Bond Activation for the Synthesis of Heterocyclic Atropisomers Yields Hedgehog Pathway Inhibitors.

Angewandte Chemie, 2018
Axially chiral 4-arylisoquinolones are endowed with pronounced bioactivity, and methods for their efficient synthesis have gained widespread attention. However, enantioselective synthesis of axially chiral 4-arylisoquinolones by means of C-H activation ...

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.
