[FeIII(TF4DMAP)Cl] can efficiently catalyze intermolecular sp3 C-H amination using aryl azides and intramolecular sp3 C-H amination of alkyl azides in moderate-to-high product yields. At catalyst loading down to 1 mol %, the reactions display high chemo- and regioselectivity with broad substrate scope and are effective for late-stage functionalization of complex natural/bioactive molecules.

This work describes the synthesis of ruthenium(IV) m-oxo porphyrin complexes of general formula [RuIV(TPP)(X)]2O which have been applied as catalysts in nitrene transfer reactions using aryl azides (ArN3) as nitrene sources. Collected data indicated that the catalytic efficiency of [RuIV(TPP)(OCH3)]2O was comparable to that of RuII(TPP)CO because of their analogous reactivity towards aryl azides to give the same catalytically active bis-imido species RuVI(TPP)(ArN)2. The reaction of [RuIV(TPP)(OCH3)]2O with Ph3CN3 or (CH3)3SiN3 afforded [RuIV(TPP)(N3)]2O which was fully characterised, its molecular structure was also determined by single crystal X-ray analysis.
Ruthenium porphyrins-catalyzed atom-efficient amination of C-H bonds by arylazides

experimental part, p. 732 - 740 (2011/11/14)
Benzylic amines are synthesized in yield up to 90% by the Ru(TPP)CO-catalyzed amination of both exocyclic and endocyclic benzylic C-H bonds. The choice of arylazides as nitrogen sources confers to the methodology a good sustainability due to the formation of molecular nitrogen as the only stoichiometric by-product. A preliminary mechanistic investigation evidenced a critical role of the hydrocarbon concentration to drive the chemoselectivity of the reaction.
