DISSOCIATION ENERGY OF THE N-H BOND IN 2,6-DIARYL-4-PHENYL-1,2,3,4-TETRAHYDRO-SYM-TETRAZINES AND THE COMPARATIVE REACTIVITY OF SYM-TETRAZINYLS IN DEHYDROGENATION OF HYDRAZOBENZENE

The equilibrium constants in the reactions of 2,6-diaryl-4-phenyl-1,2,3,4-tetrahydro-sym-tetrazines with 2,2,6,6-tetramethyl-4-oxopiperidin-1-oxyl in heptane were determined by spectrophotometric and ESR methods.The dissociation energies of the N-H bond is the sym-tetrazines were determined.Results are given which indicate that the substituents in the phenyl ring at the C6 and N2 atoms have effects substantially different and opposite in sign on the thermochemical value of the dissociation energy of the N-H bond in sym-tetrazines.The sym-tetrazines with donatingsubstituents at the C6 atom and accepting substituents at the nitrogen atom are characterized by the largest dissociation energy for the N-H bond.The kinetics of the dehydrogenation of hydrazobenzene by sym-tetrazinyls in acetonitrile were investigated.It was found that there is an inverse relationship between the activation energies of the reaction and the dissociation energy of N-H bond in sym-tetrazines.The reaction mechanism is discused.
