Photohomolysis and Photoheterolysis in Aryl Sulfonates and Aryl Phosphates

Chemistry – A European Journal, 2021
AbstractThe 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 ...

NHC-Catalyzed Desymmetrization of N-Aryl Maleimides Leading to the Atroposelective Synthesis of N-Aryl Succinimides.

Angewandte Chemie, 2021
Although the construction of axially chiral C-C bonds leading to the atroposelective synthesis of biaryls and allied compounds are well-known, the related synthesis of compounds bearing axially chiral C-N bonds are relatively rare.

SYNTHESIS OF ARYL THIOCYANATES FROM ARYL ALKYL SULPHIDES. CONVERSION OF UNACTIVATED ARYL HALIDES INTO ARYL THIOCYANATES [PDF]

open access: possiblePhosphorus and Sulfur and the Related Elements, 1983
Abstract Aryl alkyl sulphides, easily obtained from aryl halides, can be selectively dealkylated in HMPA by treatment with sodium, sodium methanethiolate or sodium methoxide. The resulting solutions, containing the sodium arenethiolates, when treated with BrCN or ICN, afford the corresponding aryl thiocyanates in moderate to good yields.

Light-Promoted Nickel Catalysis: Etherification of Aryl Electrophiles with Alcohols Catalyzed by a Ni(II)-Aryl Complex.

Angewandte Chemie, 2020
A highly effective C-O coupling reaction of (hetero)aryl electrophiles with primary and secondary alcohols is reported. Catalyzed by a Ni(II)-aryl complex under long-wave UV (390-395 nm) irradiation in the presence of a soluble amine base without any ...

Aryl Diazonium Salts: Powerful Arylating Agents for Catellani-Type ortho-Arylation

The Journal of Organic Chemistry, 2021
The 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 ...
