aromatic rings, ketones, nitriles, halides, alcohols, and esters are tolerated. Sulfides react with HOF·CH3CN usually at the same rate as azides. Amines and olefins, however, react faster, so they have to be protected first. Nitro derivatives with various oxygen isotopes can be made using the labeled H18OF·CH3CN. In the case of chiral azides the stereochemistry around the nitrogen-bonded carbons is retained

β-xylopyranosides with 8, 10, or 12 carbons caused toxicity via apoptosis, with CC50 values ranging from 26-890 μM. The two longest chain compounds did form stable monolayers at the air-waterinterface over a range of temperatures, although a brief transition to an the unstable monolayer was observed.

Synthesis, surface properties and bioactivity of novel 4-Substituted 1,2,3-Triazole quaternary ammonium surfactants
effectiveness of surface tension reduction (Πcmc), minimum surface area occupied by a molecule (Amin) at the air − water interface and standard Gibbs free energy of micellization ΔGMic0. These heterocyclic surfactants exhibit much lower CMC values as compared with those reported for conventional alkyltriethyl ammoniums and alkylbenzyldiethyl ammonium salts. Their micelles formation and surface adsorption

The generation and use of the highly potent oxidising agent HOF⋅MeCN in a controlled single continuousflowprocess is described. Oxidations of amines and azides to corresponding nitrated systems by using fluorine gas, water and acetonitrile by sequential gas–liquid/liquid–liquid continuousflow procedures are reported.
