Pd nanoparticles for C–C coupling reactions

Chemical Society Reviews, 2011
The catalytic formation of C-C bonds is one of the most useful transformations in organic synthesis. Over the last decade, the use of transition metal nanoparticles (NPs) in catalysis has attracted much interest and their use in C-C bond formation reactions constitutes one of their most important applications, including the Suzuki, Heck, and ...

Catalytic CC, CN, and CO Ullmann‐Type Coupling Reactions

Angewandte Chemie International Edition, 2009
AbstractCopper‐catalyzed Ullmann condensations are key reactions for the formation of carbon–heteroatom and carbon–carbon bonds in organic synthesis. These reactions can lead to structural moieties that are prevalent in building blocks of active molecules in the life sciences and in many material precursors.

Surface‐Dependent Chemoselectivity in C−C Coupling Reactions

Angewandte Chemie International Edition, 2019
AbstractSurface‐confined covalent coupling reactions of the linear compound 4‐(but‐3‐en‐1‐ynyl)‐4′‐ethynyl‐1,1′‐biphenyl (1), which contains one alkyne and one enyne group on opposing ends, have been investigated using scanning tunneling microscopy (STM) and density functional theory (DFT) calculations.

Polymers for Green C–C Couplings

European Journal of Inorganic Chemistry, 2011
AbstractCleaner and environmentally more friendly cross‐coupling reactions can be carried out by the use of polymers as supports. A lot of work has been devoted to attach palladium catalysts on polymers, so they can be easily separated from the reaction mixture and reused.

Nanoscale insight into C–C coupling on cobalt nanoparticles

Chemical Communications, 2014
The Ullmann coupling of bromobenzene to biphenyl on Co nanoparticles proceeds below room temperature via an intermediate in which phenyl groups are bound directly to metallic Co. A similar surface-bound benzyl intermediate is observed for coupling of benzylbromide to bibenzyl on Co.

The Liebeskind–Srogl CC Cross‐Coupling Reaction

Angewandte Chemie International Edition, 2009
AbstractNew kid on the block: The cross‐coupling of thioorganic compounds with boronic acids under neutral conditions in the presence of catalytic palladium(0) and a stoichiometric amount of a copper(I) oxygenate has emerged as a very useful method for the construction of CC bonds (see scheme).

A Decade of Electrochemical Dehydrogenative C,C-Coupling of Aryls

Accounts of Chemical Research, 2019
The importance of sustainable and green synthetic protocols for the synthesis of fine chemicals has rapidly increased during the last decades in an effort to reduce the use of fossil fuels and other finite resources. The replacement of common reagents by electricity provides a cost- and atom-efficient, environmentally friendly, and inherently safe ...

Reversible C−C Coupling in a Uranium Biheterocyclic Complex

Journal of the American Chemical Society, 2010
The C-C coupling of two molecules of 1-methylbenzimidazole was effected by a neutral uranium dibenzyl complex supported by a ferrocene 1,1'-diamide ligand. The transformation involves the C-H activation of two heterocycles and the coupling of one eta(2)-N,C-imidazolyl fragment with a coordinated 1-methylbenzimidazole ligand.
