Bufotenidinium iodide [PDF]

open access: yesIUCrData, 2021
The title compound, 5-hydroxy-N,N,N-trimethyltryptammonium (5-HTQ) iodide {systematic name: [2-(5-hydroxy-1H-indol-3-yl)ethyl]trimethylazanium iodide}, C13H19N2O+·I−, has a single tryptammonium cation and one iodide anion in the asymmetric unit. The ions are held together by N—H...I and O—H...I hydrogen bonds in infinite chains along [100].

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

Visible-light promoted atom transfer radical addition-elimination (ATRE) reaction for the synthesis of fluoroalkylated alkenes using DMA as electron-donor [PDF]

open access: yes, 2020
Here, we describe a mild, catalyst-free and operationally-simple strategy for the direct fluoroalkylation of olefins driven by the photochemical activity of an electron donor-acceptor (EDA) complex between DMA and fluoroalkyl iodides.

Solvent-Free Synthesis of Aryl Iodide Using Nano SiO2/HIO4 as a Reusable Acid Catalyst [PDF]

open access: yesJournal of Nanostructures, 2014
An efficient and environmentally benign   method for the synthesis of aryl iodides have been developed by diazotization of aromatic amines with NaNO2 and nanosilica periodic acid (nano-SPIA) as a green catalyst via grinding followed by a sandmeyer ...

Benzazole derivatives: V. The reactivity of some 2-p-tolyl-and 2-p-methylstyryl-benzimidazolium salts [PDF]

open access: yesHemijska Industrija, 2004
The reactivity of the p-substituted methyl group in 1-methyl-2-p-tolylbenzimidazolium and 1-methyl-2-p-methylstyrylbenzimidazolium iodides with p-nitroso-dimethylaniline (p-NDMA) and aromatic aldehydes was studied.

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

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.

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 ...
