Palladium-catalyzed difluoromethylation of heteroaryl chlorides, bromides and iodides. [PDF]

open access: yes, 2017
A palladium-catalyzed difluoromethylation of a series of heteroaryl chlorides, bromides and iodides under mild conditions is described. A wide range of heteroaryl halides such as pyridyl, pyrimidyl, pyrazyl, funanyl, thienyl, pyazolyl, imidazolyl ...

Long-Term Antithyroid Drug Therapy in Smoldering or Fluctuating-Type Graves’ Hyperthyroidism with Potassium Iodide [PDF]

open access: yesEndocrinology and Metabolism
Graves’ hyperthyroidism is characterized by stimulation of the thyroid gland by thyroid-stimulating hormone receptor antibodies (TRAbs). Antithyroid drug (ATD) continuation is recommended as long as the thyroid gland is stimulated. Goiter size, thyroidal

Deprotometalation-Iodolysis and Direct Iodination of 1-Arylated 7-Azaindoles: Reactivity Studies and Molecule Properties

open access: yesMolecules, 2021
Five protocols were first compared for the copper-catalyzed C-N bond formation between 7-azaindole and aryl/heteroaryl iodides/bromides. The 1-arylated 7-azaindoles thus obtained were subjected to deprotometalation-iodolysis sequences using lithium 2,2,6,

Glycerol as a cheap, safe and sustainable solvent for the catalytic and regioselective β,β-diarylation of acrylates over palladium nanoparticles [PDF]

open access: yes, 2010
Herein we show that glycerol can be considered as a promising cheap and green solvent for the regioselective β,β-diarylation of alkenes. Whereas this reaction is generally catalyzed under an inert atmosphere by expensive phosphine or carbene-palladium ...

Recent developments in the Suzuki-Miyaura reaction: 2010-2014 [PDF]

open access: yes, 2015
The Suzuki-Miyaura reaction (SMR), involving the coupling of an organoboron reagent and an organic halide or pseudo-halide in the presence of a palladium or nickel catalyst and a base, has arguably become one of most utilized tools for the construction ...
