N.m.r. spectra of fresh solutions of 1,4-benzoquinone and various, mainly chloro-substituted, derivatives in liquid ammonia are consistent with nucleophilic addition at one or both carbonyl carbon atoms and not at C(2), or equivalent positions, expected in Michael-type addition.
1,4-苯醌和各种主要被氯取代的衍生物在液氨中的新鲜溶液的Nmr光谱与在一个或两个羰基碳原子处而不是在C(2)或等价位置处的亲核加成一致,这在迈克尔中预期型加法。
