Aryl–Aryl Interactions in (Aryl‐Perhalogenated) 1,2‐Diaryldisilanes

open access: yesChemistry – A European Journal, 2020
AbstractThree 1,2‐diaryltetramethyldisilanes X5C6‐(SiMe2)2‐C6X5 with two C6H5, C6F5, or C6Cl5 groups were studied concerning the importance of London dispersion driven interactions between their aryl groups. They were prepared from 1,2‐dichlorotetramethyldisilane by salt elimination.

Reversible Dehalogenation in On‐Surface Aryl–Aryl Coupling [PDF]

open access: yesAngewandte Chemie International Edition, 2020
AbstractIn the emerging field of on‐surface synthesis, dehalogenative aryl–aryl coupling is unarguably the most prominent tool for the fabrication of covalently bonded carbon‐based nanomaterials. Despite its importance, the reaction kinetics are still poorly understood.

Synthesis of Morphinans through Anodic Aryl‐Aryl Coupling

open access: yesThe Chemical Record, 2021
AbstractThe morphinans are an important class of structurally fascinating and physiologically important natural products as exemplified by the famous opium alkaloids of the morphine family. Although this class of secondary metabolites from the juice of the opium poppy capsule was already used for medicinal purposes thousands of years ago, chemical ...

Making Blank Faces Expressive: Chemical Approaches to the Modification of Chemically Inert Peptides. [PDF]

open access: yesJ Pept Sci
As an alternative to the conventional approach, which combines amino acid monomers in a one‐by‐one fashion to peptide derivatives, the chemical modification of existing peptides has attracted significant attention in recent years. However, such approaches generally target the reactive functional groups in cysteine and lysine residues, particularly in ...

Copper-catalyzed remote C–H arylation of polycyclic aromatic hydrocarbons (PAHs)

open access: yesBeilstein Journal of Organic Chemistry, 2020
The regioselective C–H arylation of substituted polycyclic aromatic hydrocarbons (PAHs) is a desired but challenging task. A copper-catalyzed C7–H arylation of 1-naphthamides has been developed by using aryliodonium salts as arylating reagents.

Arylation Reactions in the Synthesis of Biologically Important 2,5-Diaryl-1,3,4-Oxadiazoles

open access: yesApplied Sciences, 2022
Apart from carbon atoms, some cyclic molecules contain other elements and play an extraordinary role in human life. Among these systems, 1,3,4-oxadiazole derivatives deserve special attention due to their biological properties such as antibacterial ...

Copper-Catalyzed Arylation of 1\u3cem\u3eH\u3c/em\u3e-Perfluoroalkanes [PDF]

open access: yes, 2011
A general method has been developed for arylation of readily available 1H-perfluoroalkanes. The method employs aryl iodide and 1H-perfluoroalkane reagents, DMPU solvent, TMP2Zn base, and a copper chloride/phenanthroline catalyst.
