Usage

General Description

2,4,6-trinitrophenol - pyridine (1:1) is a chemical compound formed by the combination of 2,4,6-trinitrophenol, also known as picric acid, and pyridine in a 1:1 ratio. Picric acid is a yellow, crystalline substance used as an explosive or in the manufacture of dyes and pharmaceuticals. Pyridine is a flammable, colorless liquid commonly used as a solvent and reagent in chemical reactions. When combined in a 1:1 ratio, the resulting compound can be used as a reagent in organic synthesis, specifically in the formation of picryl derivatives. It is important to handle this compound with caution due to its explosive and flammable properties.

Dynamic NMR spectroscopy of three 2,2′-dialkyl/aryl-1-picrylhydrazines in liquid solution

We have studied and compared the proton nuclear magnetic resonance spectra of a series of three 2,2′-di(alkyl/aryl)-1-(2,4,6-trinitrophenyl)hydrazines at 500 MHz in liquid toluene-d8, with a view to learning details of the internal conformation changes taking place, as a function of temperature. Herein "alkyl" denotes 'methyl', and "aryl" denotes 'phenyl'. The synthesis and characterization of 2-phenyl,2′-methyl-1-picrylhydrazine is reported. One goal of the present study was to afford a comparison with the oxidation products, i.e., the three corresponding hydrazyl free radicals - which show striking differences. All the hydrazine molecules in liquid solution occur as interconverting enantiomorphic pairs (atropisomers). Advanced techniques for obtaining the relevant activation energies and pseudo-thermodynamic parameters (Arrhenius and Eyring) have been utilized, and these parameters are listed and discussed. The three hydrazines turn out be very similar with respect to their internal dynamics.
