The reduction mechanism of two pesticides, iprodione [3 -3,5-dichlorophenyl)-N-(1-methylethyl)-2,4-dioxo-1-imidazolidinecarboxamide] and [3-(3,5-dichlorophenyl)-1,5-dimethyl-3-azabicyclo[3.1.0]hexane-2,4-dione], was studied in the absence and presence of .beta.-cyclodextrin in a dimethylsulfoxide solvent. Distribution of the reduction products changed in the presence of .beta.-cyclodextrin. The complex formation led to protection of the imidazolidine ring of iprodione against cleavage, with a subsequent decrease in aniline-type products. In the case of procymidone, the mechanism exclusively led to the formation of monochloro derivatives of the original pesticide.
