Carbon−halogen bond cleavage has been studied extensively for many years as a simple electrosynthesis step in the formation of more complex natural products. Reduction halogenated phenols received less attention, part, due to lowered faradaic efficiency resulting from competing hydrogen evolution reaction. Herein, we report electroreduction series brominated through homogeneous electrocatalytic (EC′) mechanism. Beginning with structurally 2-bromophenol, use foot-of-the-wave analysis...
First reported in the early 1930s, sonoelectrochemistry is an analytical technique that seeks to incorporate ultrasound into electrochemical experiments. Compton and co-workers reviewed numerous advantages of over “silent” experiments without ultrasound, including increased mass transport electrode surface roughening. 1 Presently, there a lack research employing study environmental remediation, topic particular interest our group. As beginning inquiry various factors optimize...
Once a widely popular insecticide, Chlorpyrifos ( O , -diethyl- -3,5,6-trichloropyridin-2-yl phosphorothioate) has been the center of controversy in recent years. Rauh and co-workers found compound to be neurotoxic; severe developmental defects were children up three years age. 1 Regardless these findings, political divide over continued use led inaction its regulation. In 2015, EPA responded petition filed 2007 by proposing complete ban on for food crops. However, reversed course 2017,...
Chloroxynil (3,5-dichloro-4-hydroxybenzonitrile), Bromoxynil (3,5-dibromo-4-hydroxybenzonitrile), and Ioxynil (3,5-diiodo-4-hydroxybenzonitrile) belong to a group of halogenated phenols commonly used as herbicides control broad-leaved weeds. Functioning disruptors oxidative phosphorylation, these compounds have grown in popularity recent years alternatives atrazine, particularly bromoxynil (1800–2200 tons applied per year). 1,2 In the environment, all three can undergo hydrolysis well...
It has been well established that silver electrodes are remarkable catalysts for the reduction of carbon–halogen bonds. The mechanism electron-transfer (concerted vs. stepwise) seems to be an important aspect electrocatalysis, as catalysis is only observed concerted processes. 1,2 For several years, it understood aliphatic halides prefer transfer, whereas aromatic stepwise transfer a result their low-lying π* orbitals. 3 However, effect adding various substituents ring on not widely studied....
Polyhalogenated phenols are a class of environmental pollutants that serve as precursors to dioxins and behave endocrine disruptors. 1,2 As result, an efficient route degradation is needed. Traditional methods remediation include microbial, thermal, chemical pathways; however, these typically require large amounts toxic solvents, excessive energy, can be tremendously time-consuming. 3 Electrochemistry has become growing area research for the environmentally-harmful compounds,...
