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 and Functionalization of C—H Bonds

2004
Activation and Functionalization of C-H Bonds explores recent developments in the reaction chemistry of solution-phase transition-metal based systems with simple hydrocarbons and with more complex organic molecules. More than 20 internationally leading research groups contributed to this volume, and their chapters cover such topics as fundamental ...

Activation of CH bonds by transition metals

Journal of Organometallic Chemistry, 1977
Abstract Reaction of R 2 PCH 2 C 6 H 5 (R = cyclohexyl or t-butyl) with [(COT) 2 RhCl] 2 , [(COT) 2 IrCl] 2 , PdCl 2 or PtCl 2 (benzonitrile) 2 yields cyclometallated compounds. The reactivity appears to decrease in the order Ir I ρ Rh I ρ ρ Pd II ≈ Pt II , suggesting a different reaction mechanism for univalent and bivalent d 8 metal atoms.

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)].
