The reduction of vinclozoline, 3-(3,5 -dichlorophenyl)-5-methyl-5-vinyl-1,3 -oxazolidine-2,4-dione, was studied in acetonitrile by electrochemical impedance and by electrolysis combined with GC/MS identification of products. The electron transfer reaction was coupled with subsequent chemical reactions yielding two final products at -2.35 V. The main decomposition pathways included the elimination of the hetero-ring, which produced chloroaniline, whereas the cleavage of one chlorine atom was a much slower process. The kinetic parameters of both chemical processes correlated reasonably well with the observed yield of dichloroaniline and dechlorovinclozoline.
