摘要: Using i.r., n.m.r. and visible spectrophotometry, the system 2,6-dimethylnitrosobenzene (DMNB)⇄ 2,2′,6,6′-tetramethylazodioxybenzene (TMAB) was investigated. In solid state, stable species is trans-TMAB. acetonitrile solution, following thermodynamic activation parameters were derived for reaction trans-TMAB ⇄ 2 DMNB ΔH°–54.0 kJ mol–1, ΔS°–129 J K–1 ΔH‡ 84.5 ΔS‡–6 mol–1. There no evidence existence of cis-TMAB in solution.
