Photolysis of aryl formates and aryl acetates
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19791. The yields of the phenols during the photolysis of a number of aryl formates and aryl acetates were determined. 2. The aroxyl radicals that are obtained during the photolysis of aryl formates and aryl acetates were recorded by the pulse photolysis method. 3. The photodissociation of aryl formates and aryl acetates proceeds

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 ...

Iron-Catalyzed Coupling of Aryl Sulfamates and Aryl/Vinyl Tosylates with Aryl Grignards
Organic Letters, 2014AbstractIn contrast to previous reports with aryl chlorides, the title coupling reaction with aryl sulfamates proceeds with low levels of the Grignard homocoupling side reaction.

The induction of expression of genes for xenobiotic metabolizing enzymes in response to chemical insult is an adaptive response found in most organisms. In vertebrates, the AhR is one of several chemical/ligand-dependent intracellular receptors that can ...

Exploiting Aryl Mesylates and Tosylates in Catalytic Mono-α-arylation of Aryl- and Heteroarylketones
Organic Letters, 2016AbstractKey to this general protocol for mono‐α‐arylation is the indolyl‐derived phosphine ligand which enhances the steric congestion of the catalyst.

C-N Cross-Couplings for Site-Selective Late-Stage Diversification via Aryl Sulfonium Salts.
Journal of the American Chemical Society, 2019We report diverse C-N cross-coupling reactions of aryl thianthrenium salts that are formed site-selectively by direct C-H functionalization. The scope of N-nucleophiles ranges from primary and secondary alkyl and aryl amines to various N-containing ...

Catalytic Scissoring of Lignin into Aryl Monomers
Advances in Materials, 2019Lignin is an aromatic polymer, which is the biggest and most sustainable reservoir for aromatics. The selective conversion of lignin polymers into aryl monomers is a promising route to provide aromatics, but it is also a challenging task.

Nickel-Catalyzed Thiolation of Aryl Halides and Heteroaryl Halides through Electrochemistry.
Angewandte Chemie, 2019Transition-metal-catalyzed coupling reactions are useful tools for synthesizing aryl sulfur compounds. However, conventional transition-metal-catalyzed thiolation of aryl bromides and chlorides typically requires the use of strong base under elevated ...
