Aromatic nucleophilic substitution reactions in 1-halo-3,5-dinitrobenzenes (where the halogen is bromine or chlorine) can occur with replacement of either a nitro group or a halogen atom, depending on the nature of anionic nucleophile Nu– as a Lewis base (hard, soft or intermediate), as well as on the polarity of the dipolar aprotic solvent.
根据阴离子亲核试剂Nu–作为路易斯碱的性质,在1-卤代3,5-二硝基苯(卤素为溴或氯)中发生芳香亲核取代反应,同时取代硝基或卤素原子(硬,软或中间)以及偶极非质子溶剂的极性。
