Spectrophotometric study of photosensitized dechlorination of isomeric mono- and dichloronitrobenzenes

Photoangeregte Anionen in organischen Reaktionen

“…[74] Mit Mono-und Dichlornitrobenzol konnten etwas später weitere Substrate umgesetzt werden. [75] Darüber hinaus wurde gezeigt, dass NA À die Detosylierung von Sulfonamiden in Gegenwart eines Überschusses an NaBH 4 als terminales Reduktionsmittel katalysiert (Schema 7, rechts). [76] Durch Anwenden dieser Methode konnten 2-Phenylethylamin (9.2)u nd N-Methylbenzylamin (9.5)a usgehend von den jeweiligen Sulfonamiden in quantitativer Ausbeute erhalten werden.…”

Enhanced biodegradation of 2‐chloronitro‐benzene using a coupled zero‐valent iron column and sequencing batch reactor system

“…Concern about ClNBs as environmental contaminants has led to intense efforts to find efficient and cost‐effective treatment methods for the remediation of these compounds 1, 3. During the last two decades, various physical and chemical processes, such as ozonation,4 photocatalysis,5 photoassisted and Fenton oxidation,6 have been utilized for the treatment of wastewater containing ClNBs. Unfortunately, most of the physicochemical treatment methods have high treatment costs or cause secondary pollution.…”

Methylene Blue Sensitized Photodechlorination of Isomeric Mono‐ and Dichloroanilines via Molecular Complex Formation Mechanism

“…Amongst all these techniques, the photochemical degradation technique has been found very effective for the decomposition of chloroanilines especially by using UV-vis radiation in different solvents [16][17] . In our previous publications, we have reported the photosensitized dechlorination of isomeric mono-and dichloronitrobenzenes, isomeric chloroanisidines and isomeric mono-and dichlorobenzoic acids [18][19][20] . .…”
