| Abstract: | The reaction mechanism of the intramolecular cycloaddition of ketenimines withimines is investigated by using AM1 method The results show that this reaction is stepwisemechanism via an intermediate and wto transition states.The firstr step is rate determining,which barrier is about 104.1kJ.mol-1. |
