Recent advances in aryl–aryl bond formation by direct arylation
Chemical Society Reviews, 2009The abundance of the biaryl structural motif in natural products, in biologically active molecules and in materials chemistry has positioned aryl-aryl (Ar-Ar) bond formation high on the agenda of synthetic chemists. For decades well-known reactions such as the Mizoroki-Heck and Suzuki-Miyaura have been the methods of choice to furnish biaryls.

Aryl Diazonium Salts: Powerful Arylating Agents for Catellani-Type ortho-Arylation
The Journal of Organic Chemistry, 2021The Catellani reaction provides an efficient synthetic approach to polyfunctionalized arenes. However, the selective ortho-arylating reagents employed in these reactions have been strictly limited to activated bromoarenes. As demonstrated in this work, aryl diazonium salts bearing both electron-donating and electron-withdrawing substituents, after in ...

N‐Arylation of Diketopyrrolopyrroles with Aryl Triflates
Chemistry – An Asian Journal, 2020AbstractA new methodology for the double N‐arylation of diketopyrrolopyrroles with aryl triflates has been developed. It is now possible to prepare diketopyrrolopyrroles bearing N‐substituents derived from naphthalene, anthracene and coumarin in two steps from commercially available phenols. This represents the first time arenes lacking strong electron‐

Arylation of Aldehyde Homoenolates with Aryl Bromides
Organic Letters, 2013A mild palladium catalyzed coupling of reactive aldehyde homoenolates with aryl bromides is described. Aldehyde homoenolates are generated by ring opening of cyclopropanols via a C-C cleavage step. The coupling generates aldehyde products at room temperature in 59-93% yield.
