摘要：
The mechanism of the title reaction has been studied al the UHF, UMP2, UMP4(sdq) and UQCISD levels of theory with the 6-311G * * basis set. The results show that the hydrogen-atom abstraction path proceeds without potential energy barrier and the trans and cis nitrogen-atom abstraction reaction paths have quite small potential energy barriers. The heat of reaction calculated at the UQCISD level is -79.83 kcal/mol. Therefore, though the hydrogen-atom abstraction reaction is the most dominant reaction path, the nitrogen-atom abstraction reaction paths should be considered in high temperature reaction kinetics.
