The Chemistry of CH Bond Activation on Diamond

Chemistry – An Asian Journal, 2010
AbstractThe surface of hydrogen‐terminated diamond resembles a solid hydrocarbon substrate. Interestingly, the CH bonds on the diamond surface are not as unreactive as that of saturated hydrocarbon molecules owing to its unique surface electronic properties.

Iron-Catalyzed C–H Bond Activation

Chemical Reviews, 2017
Catalytic C-H bond activation, which was an elusive subject of chemical research until the 1990s, has now become a standard synthetic method for the formation of new C-C and C-heteroatom bonds. The synthetic potential of C-H activation was first described for ruthenium catalysis and is now widely exploited by the use of various precious metals.

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 ...

C−H Activation for the Construction of C−B Bonds

Chemical Reviews, 2009
A number of studies were conducted to demonstrate C-H activation for the construction of C-B bonds. Investigations revealed that the conversion of C-H bonds to C-B bonds was both thermodynamically and kinetically favorable. The reaction at a primary C-H bond of methane or a higher alkene B 2(OR)4 formed an alkylboronate ester R' -B(OR)2 and the ...

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 ...

Insights into Sustainable C–H Bond Activation

2021
Over the recent past, the straight functionalization of inert C–H bond has already been identified as an advanced technique for the synthesis of organic molecules. It has provided a step-, pot- and atom-economic synthetic approach to attain structurally challenging organic scaffolds using simpler, pre-functionalized substrates by single operation and ...

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 ...

Activation of the C–H bond by metal complexes

Russian Chemical Reviews, 1990
Reactions involving the cleavage of C–H bonds by metal complexes in saturated and aromatic hydrocarbons and also in other compounds are examined. Some of these processes occur with formation of a carbon–metal bond, whilst in others the interaction of the complexes with the hydrocarbon takes place without direct contact between the metal atom and the C ...
