Systems silver iodide-sodium iodide and silver iodide-potassium iodide

open access: yesJournal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1960
The phase relations for the systems AgI-NaI and AgI-KI have been determined for the temperature range from room temperature to 685° C, using differential thermal analysis techniques. The AgI-NaI system has a eutectic at 50 mole percent NaI and 384° C. The AgI-KI system has eutectics at 20.8 and 28.5 mole percent KI and 254° C and 244° C, respectively ...

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.

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,

Acneiform dermatoses [PDF]

open access: yes, 1998
Acneiform dermatoses are follicular eruptions. The initial lesion is inflammatory, usually a papule or pustule. Comedones are later secondary lesions, a sequel to encapsulation and healing of the primary abscess.
