Study on Quantum Chemistry of the Cycle-addition Reaction of Dibromo Carbene with P-methylacetophenone

AM1 method has been employed to study the reaction pathway and to optimize structures of the reactant, product, intermediate and transition state for the cycle addition reaction of dibromo carbene with P methylacetophenone. The reaction mechanism has been determined by the theory. The result shows that the reaction is exothermic reaction, and the second step reaction is control procedure.
