There are data only for R = H and R1 = H, resulting in difference quantities of 24.4 and 27.0 kJmol-1. The enthalpy of formation of iV-ethylaniline calculated using the average of 15 and i6 and each of the two literature values for IV-methylaniline would be ca 59 and 70 kJmol-1. The former value is closer to the literature value. Perhaps we should not be surprised because the same problems that may beset combustion measurements of the enthalpy of formation of tV-mcthylanilinc are likely to be applicable to /V-cthylaniline, especially since measurements of both species appear in the same literature source.

The suggested mechanism of iV-ethylaniline conversion to benzonitrile is proved by conjugated dehydrogenation of iV-methylaniline and benzylaniline in the presence of H202 [102], Hence, data from the literature were taken into account, which confirmed the mechanism... 

Chiral Amino Alcohol Modifying Agents. A number of chiral amino alcohols have been examined as ligands for the preparation of chiral LAH reducing agents (Figure 2). The complex of (—)-iV-methylephedrine (11) with LAH has been widely studied and has shown promise for the asymmetric reduction of prochiral ketones. It has been found that addition of an achiral component such as 3,5-dimethylphenol (DMP), iV-ethylaniline (NEA), or 2-ethylaminopyridine (EAP) to the complex of LAH with (11) can enhance the enantioselectivity observed in these reductions. Both enantiomers of (11) are commercially available and the ligand can be recovered subsequent to the reaction and reused. 

Indeed, within 4 kJ mol-1, and so within the error bars, this is true and so gives us confidence in both the recent measurements of liquid and gaseous IV-ethylaniline and its 3-methyl isomer. 

In this way were prepared iV-ethylaniline (57-63%), jV-butylaniline (94-96%), and iV-butyl-p-toluidine (88 %), etc.

The reaction of PANI in its oxidized form (both in doped and undoped form) with water, resulting in the formation of superoxide, was studied with ESR spectroscopy by Otsuka et al. [506]. Electrode kinetics of various charge transfer processes at poly(o-phenylenediamine), poly(Af-methylaniline), and poly(iV-ethylaniline) were investigated by Chiba et al. [507].
