Grignard reagents add to nitrobenzene derivatives containing trichloromethyl, dichloromethyl, and monochloromethyl groups in the meta position to form σH adducts, which are either further converted through departure of a chloride anion, giving products of tele substitution, or oxidized to products of oxidative nucleophilic substitution of hydrogen.

格氏试剂与间位含有三氯甲基、二氯甲基和单氯甲基的硝基苯衍生物加成形成 σH 加合物,这些加合物要么通过氯阴离子的离开进一步转化,得到远取代的产物,要么氧化为氧化亲核取代的产物氢。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
