Conversion of anilines into azobenzenes in acetic acid with perborate and Mo(VI): correlation of reactivities

Azobenzenes are extensively used to dye textiles and leather and by tuning the substituent in the ring, vivid colours are obtained. Here, we report preparation of a large number of azobenzenes in good yield from commercially available anilines using sodium perborate (SPB) and catalytic amount of Na2MoO4 under mild conditions. Glacial acetic acid is the solvent of choice and the aniline to azobenzene conversion is zero, first and first orders with respect to SPB, Na2MoO4 and aniline, respectively. Based on the kinetic orders, UV–visible spectra and cyclic voltammograms, the conversion mechanism has been suggested. The reaction rates of about 50 anilines at 20–50?°C and their energy and entropy of activation conform to the isokinetic or Exner relationship and compensation effect, respectively. However, the reaction rates, deduced by the so far adopted method, fail to comply with the Hammett correlation. The specific reaction rates of molecular anilines, obtained through a modified calculation, conform to the Hammett relationship. Thus, this work presents a convenient inexpensive non-hazardous method of preparation of a larger number of azobenzenes, and shows the requirement of modification in obtaining the true reaction rates of anilines in acetic acid and the validity of Hammett relationship in the conversion process, indicating operation of a common mechanism.

Kinetic studies on perborate oxidation in non-aqueous media. Oxidation of diphenylamine

Solution of perborate in glacial acetic acid generates peracetic acid on aging and the peracetic acid oxidation of diphenylamine is fast. Hydrogen peroxide in glacial acetic acid does not yield peracetic acid on standing; also, the hydrogen peroxide oxida

Reactions of N-nitrosodiphenylamine with Grignard reagents. A convenient synthesis of diaryl- and dialkyl nitroxyls

N-nitrosodiphenylamine reacts with Grignard reagents forming symmetric dialkyl- or diarylhydroxylamines which are quantitatively converted into the corresponding nitroxyls by lead dioxide oxidation.
