Catalytic activation of aromatic CH bonds

Journal of Organometallic Chemistry, 1982
Abstract A new reaction is described, involving oxidative addtion of aromatic bromides to palladium(O), two successive insertions of norbornene, and ring closure to the aromatic carbon ortho to the carbon originally bearing the bromine.

Activating C–H bonds with isolated atoms

C&EN Global Enterprise, 2018
Sprinkling individual platinum atoms across a copper surface yields an energy-efficient and durable bimetallic catalyst that effectively mediates reactions involving C–H bond activation, according to a study (Nat. Chem. 2018, DOI: 10.1038/nchem.2915).

Complex activates C-H bonds in alkanes

Chemical & Engineering News Archive, 1997
Chemists at Yale University have created a new method for functionalizing alkanes. Using an organometallic reagent that mediates regioselective photochemical activation of carbon-hydrogen bonds of saturated hydrocarbons, they can break C-H bonds to yield versatile alkylboranes [Science , 277, 211 (1997)].

Cobalt-oxygen clusters activate C-H bonds

Chemical & Engineering News Archive, 1986
Evidence continues to mount that small metal clusters may serve as useful models for understanding the properties of larger metal-containing heterogeneous catalysts. One recent piece of evidence comes from the work with cobalt-oxygen clusters by Royal B. Freas at the Naval Research Laboratory, Washington, D.C., and Joseph E.

Activation of C-H Bonds: Catalytic Reactions

1999
Direct use of the carbon-hydrogen bond in organic synthesis with the aid of the homogeneous transition metal complexes has been the subject of recent interest. This review surveys some of the recent advances in the field of the transition metal-catalyzed functionalization of carbon-hydrogen bonds.
