The mutagenicity of 2,4,6-tribromoaniline was evaluated in Salmonella tester strains TA1535, TA1537, TA1538, TA98 and TA100 (Ames Test), and Saccharomyces cerevisiae strain D4, both in the presence and absence of metabolic activation by Aroclor-induced rat liver S9 fraction. Based on preliminary toxicity determinations, 2,4,6-tribromoaniline, diluted in DMSO, was tested at concentration up to 250ug/plate using the plate incorporation technique. 2,4,6-Tribromoaniline did not cause a positive response in any tester strain with or without metabolic activation.

A highly efficient and chemoselective method for the synthesis of diaryl disulfides is developed via a visible light-promoted coupling of readily accessible arenediazonium tetrafluoroborates and CS2. This practical and convenient protocol provides a direct pathway for the assembly of a series of disulfides in an environmentally friendly manner with good to excellent yields.

azobenzenes in good yield from commercially available anilines using sodiumperborate (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

Regioselective nuclear bromination of aromaticcompounds is investigated with N-bromosuccinimide as the brominating agent under UV irradiation to afford the corresponding brominated compounds. The reaction proceeds at ambient temperature (30 ± 2 °C) without any catalyst. In most of the reactions, regioselectively mono-brominated products are obtained in good to high yields. The conversion and selectivity
