The addition of 4-(N,N-dimethylamino)phenyllithium to nitroarenes in THF (−78°C) affords the corresponding diarylamines in one-pot and the reaction appears to be general in scope. A ‘nitroso’-based mechanism is proposed for this novel nitroreductive N-arylation reaction.
在THF(-78°C)中向硝基芳烃中添加4-(N,N-二甲基氨基)苯基锂可在一锅中获得相应的二芳基胺,该反应似乎是一般性的。提出了一种基于“亚硝基”的机理用于这种新型的硝基还原N-芳基化反应。
