Reacting N-aryliminophosphoranes with 1-(het)aroyl-2-aryldiazenes in preheated diphenyl ether at ca. 150-250 °C for 5-25 min affords in most cases the 1,3-diaryl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yls (aka Blatter radicals) in moderate to good yields. All new compounds are fully characterized, including EPR and CV studies for the radicals. Single-crystal X-ray structures of 1-benzoyl-2-(perfluorophenyl)diazene and 1-(perfluorophenyl)-3-phenyl-1,4-dihydrobenzo[e][1,2,4]triazinyl are also presented.
在预热的二苯醚中，N-芳基亚膦酰基与 1-(杂)芳酰基-2-偶氮苯在约 150-250°C 下反应 5-25 分钟，大多数情况下可得到中等至良好收率的 1,3-二芳基-1,4-二氢苯并[e][1,2,4]三嗪-4-基（又名 Blatter 自由基）。所有新化合物都经过了全面表征，包括自由基的 EPR 和 CV 研究。还介绍了 1-苯甲酰基-2-(全氟苯基)偶氮苯和 1-(全氟苯基)-3-苯基-1,4-二氢苯并[e][1,2,4]三嗪基的单晶 X 射线结构。
