The present invention provides novel transition metal complexes (e.g., complexes of any one of Formulae (C1) to (C25)) that include an amine-N-oxide motif. The invention also provides methods of using these transition metal complexes in preparing N-aryl or N- heteroaryl sulfonimides (e.g., compounds of Formula (I)) and aryl or heteroaryl amines (e.g., compounds of Formula (II)). The inventive methods involve imidation of arenes and heteroarenes (e.g., compounds of Formula (A)) using an imidating agent (e.g., a compound of Formula (B), such as N-fluorobenzenesulfonimide (NFBS or NFSI)) in the presence of a single-electron reductant (e.g., an Ag(I) or Ru(II) salt).
本发明提供了新型过渡金属配合物(例如,任一公式(C1)至(C25)中的配合物),其中包括胺-N-氧化物基团。该发明还提供了使用这些过渡金属配合物制备N-芳基或N-杂芳基磺酰亚胺(例如,公式(I)中的化合物)和芳基或杂芳基胺(例如,公式(II)中的化合物)的方法。创新方法涉及使用一种咪唑化试剂(例如,公式(B)中的化合物,如N-氟苯磺酰亚胺(NFBS或NFSI))在单电子还原剂(例如,Ag(I)或Ru(II)盐)存在下对芳烃和杂芳烃(例如,公式(A)中的化合物)进行咪唑化。
