    Abstract: The polyhalonitrobenzenes bearing but a single halogen atom at either, but not both, of those molecular sites ortho to the nitro substituent thereof, are dehalohydroxylated to form their corresponding 2-nitrohalophenols in the presence of an ortho orienting liquid organic reaction medium.

    Abstract translation: 在邻位取代的液体有机反应介质的存在下,在其硝基取代基邻位的那些分子位点(但不是两个)上带有单卤素原子的多卤代硝基苯被脱卤羟基化以形成它们相应的2-硝基卤代苯酚。
