Facile Solvent-Free Mechanochemical Synthesis of UI3 and Lanthanoid Iodides

open access: yesChemistry, 2022
Lewis base-free lanthanoid (Ln) and actinoid (An) iodides are difficult to obtain, as standard protocols describe syntheses in solutions of donor solvents which are ultimately hard to remove. We have now established a mechanochemical approach towards the

Catalytic System for Cross-Coupling of Heteroaryl Iodides with a Nitronyl Nitroxide Gold Derivative at Room Temperature

open access: yesMolecules, 2023
A simple and highly effective methodology for the cross-coupling of heteroaryl iodides with NN–AuPPh3 at room temperature is reported. The protocol is based on a novel catalytic system consisting of Pd2(dba)3·CHCl3 and the phosphine ligand MeCgPPh having

Studies on the composition of glyceryl ethers and their preparation from diacyl glyceryl ethers in liver oils*

open access: yesJournal of Lipid Research, 1963
Procedures are described for the preparation of alkyl iodides from fatty alcohols and glyceryl ethers. Alkyl iodides were separated directly by gas-liquid chromatography (GLC) on ethylene glycol succinate columns and do not require calibration factors in

Nickel-Catalyzed Carbonylative Synthesis of Functionalized Alkyl Iodides

open access: yesiScience, 2018
Summary: Functionalized alkyl iodides are important compounds in organic chemistry and biology. In this communication, we developed an interesting nickel-catalyzed carbonylative synthesis of functionalized alkyl iodides from aryl iodides and ethers. With

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,
