Amine and azo

Generally, the addition of chlonne or bromine to tnfluoroacetonitrile leads to a mixture of partially halogenated imines, amines and azo alkanes [270, 271] In special cases, such as the HgF2-mediated addition of bromine, N,N dihaloper-fluoro-2-alkylamines can be obtained in good yields [272]... [Pg.876]

The other reaction mixtures were analyzed by GLC (OV 101 FID). In these cases it was possible to identify the following compounds substrate, dehalogenated nitro compound, desired aniline dehalogenated aniline. Two reaction intermediates (hydroxy I amine and azo- or hydrazo-compound) were determined as a sum. The selectivities given were determined at the end of the hydrogenation and are defined as... [Pg.322]

Since both molar volume and refractive index are influenced by the actual molecular species present in a solution, molar refraction has some potential value for studying association equilibria. Giles and co-workers (65-68) correlated the method with dielectric constant measurements, and have been the most active users of refractive index for studying compound formation. Reference 68 reviews earlier work (which is sketchy) and lists about forty systems (mostly oxygen containing compounds) that were studied. References 65-67 deal with amide, amine, and azo compounds, plus esters and additional work on alcohols, aldehydes, ketones, and carbohydrates. The method is simple the refractive index of a series of mixtures of varying composition but constant concentration in a solvent is measured. Compound formation is shown by a change in the slope of the n vs. mole fraction plot, such as in Fig. 2-15. [Pg.55]

Meth-Cohn and co-workers derived strong chemical support for the singlet nitrene carbazole pathway from a study of the thermolysis and photolysis of the azide 246.306 Here, the nitrene 247 has two intramolecular pathways open to it, namely, formation of carbazole (249) or phenanthridine (250) apart from intermolecular reactions leading to amine and azo compound (Scheme 48). [Pg.313]

N NMR spectra were only described for 1-aryl-3,3-dialkyltriazenes. The signal due to the central nitrogen in RN NpNyR 2 appears at the lowest field. The average shifts of the other nitrogens with respect to Np are 97 to 115 ppm for N and 258 to 293 ppm for N [21 to 23]. A comparison with the shifts of free amines and azo compounds shows for... [Pg.160]
