A method for making a substituted benzene compound includes reacting a 2-substituted benzenesulfonate or the 2-substituted benzenesulfonate further substituted in the 3, 4 or 5-position with a lithium compound to form an intermediate; and reacting the intermediate with an electrophile to form a 2,6-disubstituted benzenesulfonate or a 2,6-disubstituted benzenesulfonate further substituted in the 3, 4 or 5-position.
制备取代苯化合物的方法包括将2-取代苯磺酸盐或在3、4或5位进一步取代的2-取代苯磺酸盐与锂化合物反应以形成中间体;然后将中间体与亲电试剂反应,形成2,6-二取代苯磺酸盐或在3、4或5位进一步取代的2,6-二取代苯磺酸盐。
