Journal ArticleDOI
Highly efficient and mild copper-catalyzed N- and C-arylations with aryl bromides and iodides.
TL;DR: The new method reported here is the most successful to date with regard to Ullmann-type arylation of some of these nucleophiles, providing the arylated products under particularly mild conditions.
Journal ArticleDOI
Mild Conditions for Copper‐Catalysed N‐Arylation of Pyrazoles
TL;DR: Copper-catalysed Narylation of pyrazoles with aryl or heteroaryl bromides or iodides, which can include functional substituents, was performed under the mildest conditions yet described, by the use as catalyst of a combination of cuprous oxide with a set of inexpensive, chelating oxime-type ligands not previously known to promote such reactions.
Journal ArticleDOI
A General and Mild Ullmann-Type Synthesis of Diaryl Ethers
TL;DR: An efficient method for the synthesis of diaryl ethers under particularly mild conditions is described, and inexpensive ligands were found to greatly accelerate the Ullmann-type coupling of aryl bromides or iodides with phenols.
Journal ArticleDOI
Mild and Efficient Copper-Catalyzed Cyanation of Aryl Iodides and Bromides
TL;DR: An efficient copper-catalyzed cyanation of aryl iodides and bromides is reported, which combines catalytic amounts of both copper salts and chelating ligands and the use of acetone cyanohydrin as the cyanating agent in copper-mediated cyanation reactions.
Journal ArticleDOI
Mild Conditions for Copper‐Catalyzed Coupling Reaction of Phenols and Aryl Iodides and Bromides
TL;DR: In this paper, the Ullmann-type synthesis of diaryl ethers was shown to operate at 60-80 °C, the lowest temperatures reported to date for an Ullman type synthesis.
