Beschreibung
Zusammenfassung:	The present invention relates to a process for resolution of Chlocyphos of Formula (I) to obtain corresponding (S)- or (R)- isomers. The present invention further relates to a process of obtaining (S)-Chlocyphos using (R)-(+)-α-methylbenzylamine and (R)-Chlocyphos using (S)-(-)-α-methylbenzylamine. The said resolution process provides the corresponding isomer with chiral purity more than 98%. La présente invention concerne un procédé de résolution de Chlocyphos de Formule (I) pour obtenir des isomères (S) ou (R) correspondants. La présente invention concerne en outre un procédé d'obtention de (S)-Chlocyphos à l'aide de (R)- (+)-α-méthylbenzylamine et de (R)-Chlocyphos à l'aide de (S)-(-)-α-méthylbenzylamine. Ledit procédé de résolution produit l'isomère correspondant avec une pureté chirale supérieure à 98 %.
