Kinetics and Mechanism of Thermal Decomposition of 5-Dinitromethyl-2-methyltetrazole Derivatives

摘要

5-Ninitormethyl-2-methyltetrazole derivatives in the melt and in dibutyl phthalate decompose homolytically by a first-order reaction involving primary C-NO_2 bond cleavage in the dinitromethyl function. Introduction of bulky substituents (Br, Cl, I) in the dintriomethyl function increases the decomposition rate constant. The rate constants and the activation energies of the decomposition of dinitro-substituted tetrazoles correlate with steric constants.
