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‐

Photohomolysis and Photoheterolysis in Aryl Sulfonates and Aryl Phosphates
Chemistry – A European Journal, 2021AbstractThe photochemical behaviour of selected aryl sulfonates and phosphates (ArOX) in polar and nonpolar media has been investigated by laser flash photolysis (LFP) experiments. Two main pathways have been identified, namely the photohomolysis of the ArO−X bond or the photoheterolysis of the Ar−OX bond depending on the nature of the leaving group ...

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.

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.

Arylation Chemistry for Bioconjugation [PDF]
Angewandte Chemie - International Edition, 2019 Abstract Bioconjugation chemistry has been used to prepare modified biomolecules with functions beyond what nature intended. Central to these techniques is the development of highly efficient and selective bioconjugation reactions that operate under mild, biomolecule compatible conditions.

Deoxygenative Arylation of Carboxylic Acids by Aryl Migration
Chemistry – A European Journal, 2019AbstractAn unprecedented deoxygenative arylation of aromatic carboxylic acids has been achieved, allowing the construction of an enhanced library of unsymmetrical diaryl ketones. The synergistic photoredox catalysis and phosphoranyl radical chemistry allows for precise cleavage of a stronger C−O bond and formation of a weaker C−C bond by 1,5‐aryl ...

Exploiting Aryl Mesylates and Tosylates in Catalytic Mono-α-arylation of Aryl- and Heteroarylketones
Organic Letters, 2016The first general palladium catalyst for the catalytic mono-α-arylation of aryl- and heteroarylketones with aryl mesylates and tosylates is described. The newly developed indolyl-derived phosphine ligand L7 has been identified to promote this reaction efficiently.
