Ligand-free Nickel-catalyzed carboxylate O-arylation: Mechanistic in-sight into NiI/NiIII cycles [PDF]

open access: yes, 2022
Nickel-catalyzed cross-coupling reactions have become a powerful methodology to construct C–heteroatom bonds. How-ever, many protocols suffer from competitive off-cycle reaction pathways and require non-equimolar amounts of cou-pling partners to suppress

Complexity-Generating Transformations Enabled by Intramolecular Radical Migration: Alkyl–Arylation of Simple Olefins [PDF]

open access: yes, 2023
A free-radical cascade approach has enabled the develop-ment of a synthetically versatile alkyl–arylation of olefins. This transformation engages an excellent range of olefins, from mono- to tetrasubstituted, without requiring directing or electronically

Boron Arylations of Subporphyrins with Aryl Zinc Reagents [PDF]

open access: yesChemistry – A European Journal, 2016
AbstractBoron arylations of B‐(methoxo)triphenylsubporphyrin have been developed with a combined use of ArZnI⋅LiCl and trimethylsilyl chloride. Aryl zinc reagents bearing bromo, cyano, amide, and ester groups can be employed for the B‐arylation reaction to provide the corresponding B‐arylated subporphyrins in moderate yields.

Palladium-Catalyzed C–H Arylation of 1,2,3-Triazoles

open access: yesMolecules, 2016
Palladium(II) acetate, in combination with triphenylphosphine, catalyzes direct arylation of 1,4-disubstituted 1,2,3-triazoles effectively. This C–H arylation reaction provides facile access to fully substituted triazoles with well-defined regiochemistry.

Photoinduced synthesis of unsymmetrical diaryl selenides from triarylbismuthines and diaryl diselenides

open access: yesBeilstein Journal of Organic Chemistry, 2013
A novel method of photoinduced synthesis of unsymmetrical diaryl selenides from triarylbismuthines and diaryl diselenides has been developed. Although the arylation reactions with triarylbismuthines are usually catalyzed by transition-metal complexes ...
