2-[(polyfluorobenzylidene)amino]phenols in ethanol in the presence of triethylamine affords the corresponding fluorinated dibenz[b,f][1,4]oxazepines in moderate to high yields. The structures of 2-[(2,3,4,5,6-pentafluorobenzylidene)amino]phenol and 1,2,3,4-tetrafluorodibenzo[b,f][1,4]oxazepine have been determined by single-crystal X-ray diffraction.
在三乙胺的存在下,在乙醇中对2-[((聚氟亚苄基)氨基]苯酚进行热解,可以中等至高收率得到相应的氟化二苯并[ b,f ] [1,4]氧杂ze庚因。用单晶法测定了2-[((2,3,4,5,6-五氟亚苄基)氨基]苯酚和1,2,3,4-四氟二苯并[ b,f ] [1,4]奥氮平的结构X射线衍射。
