Kinetics of the acid catalyzed decomposition of fifteen 1-substituted-1,3-diphenyl-3-methyltriazenes have been studied in 40% aqueous ethanolic buffers at 25 °C. The slope found for the dependence log kobsvs pH of the buffer is not equal to unity, and a method of treating such experimental data is suggested. The reaction constant found (ρ = -3.70) indicates that substituents have similar effects on both protonation and decomposition of the triazene chain.
