On-Surface Cross-Coupling Reactions

The Journal of Physical Chemistry Letters, 2023
On-surface synthesis, as a bottom-up synthetic method, has been proven to be a powerful tool for atomically precise fabrication of low-dimensional carbon nanomaterials over the past 15 years. This method relies on covalent coupling reactions that occur on solid substrates such as metal or metal oxide surfaces under ultra-high-vacuum conditions, and the

Cross-Coupling Reactions of Nitroarenes

Accounts of Chemical Research, 2021
Cross-coupling reactions are powerful synthetic tools to construct diverse chemical bonds often found in, for example, advanced materials and pharmaceuticals. Since their discovery, haloarenes have habitually been used as electrophilic coupling partners both in academic and industrial contexts.

Iron-Catalyzed Cross-Coupling Reactions

Journal of the American Chemical Society, 2002
Simple iron salts such as FeCl(n), Fe(acac)(n) (n = 2,3) or the salen complex 4 turned out to be highly efficient, cheap, toxicologically benign, and environmentally friendly precatalysts for a host of cross-coupling reactions of alkyl or aryl Grignard reagents, zincates, or organomanganese species with aryl and heteroaryl chlorides, triflates, and ...

Negishi cross-coupling reaction

2002
The Negishi cross-coupling reaction is the nickel- or palladium-catalyzed coupling of organozinc compounds with various halides or triflates (aryl, alkenyl, alkynyl, and acyl).

First Cross-Coupling Reactions on Tetrazines

Organic Letters, 2003
[reaction: see text] A series of substituted chlorotetrazines were reacted with different terminal alkynes under Sonogashira or Negishi coupling conditions to furnish alkynyl-tetrazines in good to moderate yield. The electron-donating properties of the substituent on the tetrazine core were found to have a significant influence on the success of the ...

Cobalt-catalyzed cross-coupling reactions

Chemical Communications, 2008
In the last few years, we and other groups have demonstrated that economical cobalt salts can advantageously replace expensive and toxic catalysts for cross coupling reactions. These cobalt-catalyzed reactions have considerably extended the range of functionalized compounds.

Nanocatalysts for Suzuki cross-coupling reactions

Chemical Society Reviews, 2011
This critical review deals with the applications of nanocatalysts in Suzuki coupling reactions, a field that has attracted immense interest in the chemical, materials and industrial communities. We intend to present a broad overview of nanocatalysts for Suzuki coupling reactions with an emphasis on their performance, stability and reusability. We begin

Cross-Coupling Reactions of Alkenylsilanols with Fluoroalkylsulfonates

Organic Letters, 2002
[reaction: see text] The design and development of an effective protocol for the palladium-catalyzed cross-coupling of (E)- and (Z)-heptenyldimethylsilanols with organo-triflates and nonaflates is described. Optimization of this coupling focused on the issues of both reactivity and stability of the psuedohalides in the presence of the nucleophilic ...

Introduction to Cross-Coupling Reactions

2002
The cross-coupling reaction of organometallic reagents with organic electrophiles in the presence of group 8– 10 metal catalysts, notably nickel and palladium complexes, is the method of choice for a wide range of C-C, C-H, C-N, C-O, C-S, C-P or C-M bond-forming process [1].
