    摘要： The invention is directed at a new process for the preparation of pure enantiomers from the racemate of amidoacetonitrile compounds of formula (I) wherein R1, R2 and R3, independently of each other, signify hydrogen, halogen, nitro, cyano, C1-C6­-alkyl, halogen-C1-C6-alkyl, C1-C6-alkoxy, halogen-C1-C6-alkoxy, C2-C6-alkenyl, halogen-C2­-C6-alkenyl, C2-C6-alkinyl, halogen-C2-C6-alkinyl, C2-C6-alkenyloxy, halogen-C2-C6-alkenyloxy, C1-C6-alkylthio, halogen-C1-C6-alkylthio, C1-C6-alkylsulfonyloxy, halogen-C1-C6-alkylsulfonyloxy, C1-C6-alkylsulfinyl, halogen-C1-C6-alkylsulfinyl, C1-C6-alkylsulfonyl, halogen-C1-C6­alkylsulfonyl, C1-C6-alkenylthio, halogen-C1-C6-alkenylthio, C1-C6-alkenylsulfinyl, halogen-C1­-C6-alkenylsulfinyl, C1-C6-alkenylsulfonyl, halogen-C1-C6-alkenylsulfonyl, C1-C6-alkylamino, di-(C1-C6-alkyl)amino, C1-C6-alkylaminocarbonyl, di-(C1-C6-alkyl)aminocarbonyl, C1-C6-alkylsulfonylamino, halogen-C1-C6-alkylsulfonylamino, C1-C6-alkylcarbonyl, halogen-C1-C6-alkylcarbonyl, C1-C6-alkoxycarbonyl, unsubstituted or one- to five-fold substituted phenyl, unsubstituted or one- to five-fold substituted phenoxy, unsubstituted or one- to five-fold substituted phenylacetylenyl, unsubstituted or one- to four-fold substituted pyridyloxy, unsubstituted or one- to four-fold substituted pyridyl or unsubstituted or one- to seven-fold substituted naphthyl, the substituents in each case being selected from the group consisting of halogen, nitro, cyano, C1-C6-alkyl, halogen-C1-C6-alkyl, C1-C6-alkoxy and halogen-C1-C6-alkoxy, which are useful in the control of endo- and ectoparasites in and on warm-blooded animals, especially productive livestock and domestic animals, as well as on plants.
