Direct Arylation in the Presence of Palladium Pincer Complexes [PDF]

open access: yesMolecules, 2021
Direct arylation is an atom-economical alternative to more established procedures such as Stille, Suzuki or Negishi arylation reactions. In comparison with other palladium sources and ligands, the use of palladium pincer complexes as catalysts or pre ...

Rhodium-catalyzed selective direct arylation of phosphines with aryl bromides [PDF]

open access: yesNature Communications, 2022
The widespread use of biaryl monophosphines is frequently hampered by the challenges associated with their modular preparation. Here, the authors report a protocol that appends arenes to arylphosphines to access a series of these compounds via rhodium ...

Direct Arylation of Thiazoles on Water

open access: yesAngewandte Chemie - International Edition, 2007
Wetter is better: The direct arylation of thiazoles on water is quicker, cleaner, and higher-yielding than arylation in organic solvents. The reaction works under mild conditions for an array of aryl iodides, producing 2,5-diaryl thiazoles in excellent yields.

Direct Arylation Synthesis of Small Molecular Acceptors for Organic Solar Cells [PDF]

open access: yesMolecules, 2023
In recent years, small molecular acceptors (SMAs) have extensively promoted the progress of organic solar cells (OSCs). The facile tuning of chemical structures affords SMAs excellent tunability of their absorption and energy levels, and it gives SMA ...

Direct C–H Arylation

open access: yesCHIMIA, 2022
Bonds between hydrogen and carbon atoms are the most frequent type of bonds in organic molecules. The ability to replace hydrogen atoms by making other types of bonds to carbon atoms can enable simpler access to complex organic molecules by substituting

Room-temperature Pd/Ag direct arylation enabled by a radical pathway [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2020
Direct arylation is an appealing method for preparing π-conjugated materials, avoiding the prefunctionalization required for traditional cross-coupling methods. A major effort in organic electronic materials development is improving the environmental and

“On Water” Palladium Catalyzed Direct Arylation of 1H-Indazole and 1H-7-Azaindazole [PDF]

open access: yesMolecules, 2020
The C3 direct arylation of 1H-indazole and 1H-7-azaindazole has been a significant challenge due to the lack of the reactivity at this position. In this paper, we describe a mild and an efficient synthesis of new series of C3-aryled 1H-indazoles and C3 ...

An easy direct arylation of 5-pyrazolones [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2013
A mild, efficient and catalytic ligand-free method for the direct arylation of 5-pyrazolones by Pd-catalyzed C–H bond activation is reported. The process smoothly proceeds and yields are moderate to excellent.

Novel Diketopyrrolopyrrole-Based π-Conjugated Molecules Synthesized Via One-Pot Direct Arylation Reaction [PDF]

open access: yesMolecules, 2019
Diketopyrrolopyrrole (DPP) is an important type of π-conjugated building block for high-performance organic electronic materials. DPP-based conjugated materials are usually synthesized via Suzuki, Stille, or Negishi cross-coupling reactions, which ...
