Kinetic Studies on the Decomposition of Most Typical Meisenheimer Complex of Sodium 1,1-Dimethoxy-2,4,6-trinitrocyclohexadienide in Methanol

The whole decomposition of the Meisenheimer complex formed from 2,4,6-trinitroanisole (TNA) and sodium methoxide proceeds in three steps and obeys the first-order kinetics in each step.The rate of the whole decrease of concentration of the complex is given by -d(+->)/dt=(k₁+>+k₂)*+(k₃+>+k₄)*->-k₅->*, where k denotes a rate constant.This leads to the modification of the conventional unimolecular mehanism shown by TNA*CH3O^- -> TNA +CH3O^-.
