Double Carbon−Hydrogen Activation of 2-Vinylpyridine: Synthesis of Tri- and Pentanuclear Clusters Containing the μ-NC\u3csub\u3e5\u3c/sub\u3eH\u3csub\u3e4\u3c/sub\u3eCH═C Ligand [PDF]
Reactions of 2-vinylpyridine with the triruthenium complexes [Ru3(CO)12] and [Ru3(CO)10(μ-dppm)] leads to a previously unknown double carbon−hydrogen bond activation of the β-carbon of the vinyl group to afford the pentaruthenium and triruthenium ...

Long-Range C–H Bond Activation by Rh^(III)-Carboxylates [PDF]
Traditional C–H bond activation by a concerted metalation–deprotonation (CMD) mechanism involves precoordination of the C–H bond followed by deprotonation from an internal base. Reported herein is a “through-arene” activation of an uncoordinated benzylic

Visible light-driven C−H activation and C–C coupling of methanol into ethylene glycol
Direct transformation of methanol into two- or multi-carbon compounds is extremely attractive but remains a challenge. Here, the authors report an efficient photocatalytic route to the transformation of methanol into ethylene glycol and hydrogen over a ...

Probing the C-H Activation of Linear and Cyclic Ethers at (PNP)Ir [PDF]
Interaction of the amido/bis(phosphine)-supported (PNP)Ir fragment with a series of linear and cyclic ethers is shown to afford, depending on substrate, products of α,α-dehydrogenation (carbenes), α,β-dehydrogenation (vinyl ethers), or decarbonylation ...

Oxidation of Organometallic Platinum and Palladium Complexes Obtained from C−H Activation [PDF]
η^3-Cyclohexenyl and -indenyl Pt(II) and Pd(II) diimine complexes, which are generated via C−H activation of cyclohexene and indene by Pt and Pd hydroxy dimers, are selectively oxidized by Br_2, Na_2PtCl_6, and CuCl_2 to give halogenated organic products

Stereoselective Radical Translocations
The stereochemical outcome of intramolecular radical mediated hydrogen transfer (= radical translocation) is discussed. Low to excellent levels of stereocontrol are observed making such processes attractive for applications in target-oriented ...
