The reduction mechanism of vinclozoline, 3-(3,5-dichlorophenyl)-5-methyl-5-vinyl-1,3-oxazolidine-2,4-dione, was studied in a nonaqueous environment in the presence of -cyclodextrin (CD) by electrochemical methods combined with GC/MS identification of the reaction products. UV–vis measurements confirmed the formation of a 1:1 complex between vinclozoline and CD. The reduction mechanism of vinclozoline changes in the presence of CD from a predominant formation of 3,5-dichloroaniline to the formation of dechlorinated products. The CN bond between the phenyl and oxazolidine rings remains intact during the redox process.

Abstract
The reduction mechanism of vinclozoline, 3-(3,5-dichlorophenyl)-5-methyl-5-vinyl-1,3-oxazolidine-2,4-dione, was studied in a nonaqueous environment in the presence of -cyclodextrin (CD) by electrochemical methods combined with GC/MS identification of the reaction products. UV–vis measurements confirmed the formation of a 1:1 complex between vinclozoline and CD. The reduction mechanism of vinclozoline changes in the presence of CD from a predominant formation of 3,5-dichloroaniline to the formation of dechlorinated products. The CN bond between the phenyl and oxazolidine rings remains intact during the redox process.File in questo prodotto:
