Ligand-Controlled, Tunable Silver-Catalyzed C–H Amination
The development of readily tunable and regioselective C-H functionalization reactions that operate solely through catalyst control remains a challenge in modern organic synthesis. Herein, we report that simple silver catalysts supported by common nitrogenated ligands can be used to tune a nitrene transfer reaction between two different types of C-H bonds. The results reported herein represent t...
متن کاملPd(II)-catalyzed amination of C-H bonds using single-electron or two-electron oxidants.
Pd(II)-catalyzed intramolecular amination of arenes is developed using either a one- or two-electron oxidant. The reaction protocol tolerates a wide range of deactivating groups including acetyl, cyano, and nitro groups. This catalytic reaction allows expedient syntheses of broadly useful substituted indolines or indoles.
متن کاملRhodium-catalyzed intermolecular C-H amination of simple hydrocarbons using the shelf-stable nonafluorobutanesulfonyl azide.
A new procedure has been developed for the direct intermolecular C-H amination of simple hydrocarbons using shelf-stable nonafluorobutanesulfonyl azide in the presence of a dirhodium(II) tetracarboxylate catalyst under mild reaction conditions. Some mechanistic details are briefly discussed on the basis of control experiments.
متن کاملEntrapment of a dirhodium tetracarboxylate unit inside the aromatic bowl of a calix[4]arene: unique catalysts for C-H amination.
Unique calix[4]arene-derived, tetracarboxylate dirhodium(II) inclusion complexes have been prepared and evaluated as catalysts for C-H amination.
متن کاملRhodium-catalyzed direct C-H amination of benzamides with aryl azides: a synthetic route to diarylamines.
No muss, no fuss: A rhodium-catalyzed direct intermolecular C-H amination of benzamides and ketoximes using aryl azides as the amine source has been developed. The reaction exhibits a broad substrate scope with excellent functional-group tolerance, requires no external oxidants, releases N(2) as the only by-product, and produces diarylamines in high yields.
