SYNTHESIS 2011, No. 20, pp 3209–3219xx.xx.2011 Advanced online publication: 07.09.2011 DOI: 10.1055/s-0030-1260212; Art ID: E69311SS © Georg Thieme Verlag Stuttgart · New York Abstract: The direct functionalization of pyridine and related azine derivatives through carbon–carbon bond-forming reactions is reviewed. Various transformations that use a variety of transitionmetal catalysts are covere...
متن کاملVisible light-promoted metal-free C-H activation: diarylketone-catalyzed selective benzylic mono- and difluorination.
We report herein an operationally simple method for the direct conversion of benzylic C-H groups to C-F. We show that visible light can activate diarylketones to abstract a benzylic hydrogen atom selectively. Adding a fluorine radical donor yields the benzylic fluoride and regenerates the catalyst. The selective formation of mono- and difluorination products can be achieved by catalyst control....
متن کاملTransition metal-catalyzed carbon-carbon bond activation.
This tutorial review deals with recent developments in the activation of C-C bonds in organic molecules that have been catalyzed by transition metal complexes. Many chemists have devised a variety of strategies for C-C bond activation and significant progress has been made in this field over the past few decades. However, there remain only a few examples of the catalytic activation of C-C bonds...
متن کاملRecent Advances in Transition-Metal-Catalyzed, Directed Aryl C–H/N–H Cross-Coupling Reactions
Abstract Amination and amidation of aryl compounds using a transition-metal-catalyzed cross-coupling reaction typically involves prefunctionalization or preoxidation of either partner. In recent years, a new class of transition-metal-catalyzed cross-dehydrogenative coupling reaction has been developed for the direct formation of aryl C–N bonds. This short review highlights the substantial progr...
متن کاملRuthenium-Catalyzed meta-Selective C—H Bromination
The first example of a transition-metal-catalyzed, meta-selective C-H bromination procedure is reported. In the presence of catalytic [{Ru(p-cymene)Cl2 }2 ], tetrabutylammonium tribromide can be used to functionalize the meta C-H bond of 2-phenylpyridine derivatives, thus affording difficult to access products which are highly predisposed to further derivatization. We demonstrate this utility w...
