The Mediated Reduction of Lindane in DMF

Abstract

The direct and mediated reductions of the hexachlorocyclohexane, lindane, in DMF are reported. 9,10-diphenylanthracene (DPA) is a particularly effective mediator. The reaction of DPA À with lindane is a very fast reaction and, indeed, with ratios of [lindane]/[DPA] < 5, the mediated reduction of lindane is mass transfer limited with respect to lindane. During the mediated reduction, light emission can be seen even in an undarkened laboratory; this is due to the formation of DPA*.

Silver nanoparticle decorated polyaniline–zeolite nanocomposite material based non-enzymatic electrochemical sensor for nanomolar detection of lindane

“…Table 2. 28,29,[32][33][34] It is clear from Table 2 that the present sensor is able to detect lindane with a wide linear range, low limit of detection, and high sensitivity when compared to literature reports.…”

“…This shows that lindane undergoes a diffusion controlled reduction process. 28 Mechanism of lindane reduction can be studied with the help of voltammetric response.…”

“…Birkin et al 59 also identified that benzene as the final product, but did not comment on the concentration observed or overall conversion from γ -HCH.…”

“…A single reduction peak at Ep = −1.94 V (vs. the aqueous Ag/AgCl reference electrode) was recorded. Birkin et al 59 concluded that the reduction of lindane involved a concerted six-electron transfer with no intermediates, as shown in Equation 12: C 6 H 6 Cl 6 + 6 e − → C 6 H 6 + 6 Cl −…”

“…Birkin et al 59 investigated electrochemical reduction of 1 mM lindane in dimethylformamide (DMF) with 0.1 M tetrabutylammonium tetrafluoroborate. A stationary carbon disk (0.07 cm 2 ) was used as the working electrode, a Pt spiral electrode was used as the counter electrode, and aqueous Ag/AgCl served as the reference electrode.…”
