Recent advances in aryl–aryl bond formation by direct arylation

Chemical Society Reviews, 2009
The 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.

Scope of direct arylation of fluorinated aromatics with aryl sulfonates

Organic & Biomolecular Chemistry, 2012
The scope and limitations of direct arylation of fluorinated aromatics with aryl sulfonates was examined. Pd(OAc)(2), in the presence of MePhos and KOAc in THF, efficiently catalyzed the direct arylation of fluoro aromatics with aryl triflates under ambient conditions. Sterically hindered triflates and heteroaryl triflates gave good to excellent yields

Direct Arylation of Benzothiazoles and Benzoxazoles with Aryl Boronic Acids

Chemistry – A European Journal, 2011
Direct arylation of benzothiazole (IV) and benzoxazole (I) with a wide range of arylboronic acids is smoothly achieved in the presence of a Pd—Cu cocatalyst under aerobic conditions.

Nickel-Catalyzed Direct Arylation of Azoles with Aryl Bromides

Organic Letters, 2009
Nickel catalyst systems for the direct C2 arylation of oxazoles and thiazoles have been developed. The catalyst systems are cost-efficient and allow the use of various aryl bromides in the C-H arylation of azoles.

Palladium-Catalyzed Direct Arylation of Methyl Sulfoxides with Aryl Halides

Journal of the American Chemical Society, 2013
The palladium-catalyzed α-arylation of unactivated sulfoxides has been developed. The weakly acidic α-protons of sulfoxides are reversibly deprotonated by LiOtBu, and a palladium phosphine complex facilitates the arylation. A variety of aryl methyl sulfoxides were coupled with aryl bromides.

Catalytic Direct β-Arylation of Simple Ketones with Aryl Iodides

Journal of the American Chemical Society, 2013
Herein we report a direct β-arylation of simple ketones with widely available aryl iodides, combining palladium-catalyzed ketone oxidation, aryl-halide activation, and conjugate addition through a single catalytic cycle. Simple cyclic ketones with different ring-sizes, as well as acyclic ketones, can be directly arylated at the β-position with complete
