Synthesis and catalytic activity of μ-oxo ruthenium(IV) porphyrin species to promote amination reactions

Abstract

This work describes the synthesis of ruthenium(IV) [Formula: see text]-oxo porphyrin complexes of general formula [RuIV(TPP)(X)]2O which have been applied as catalysts in nitrene transfer reactions using aryl azides (ArN[Formula: see text] as nitrene sources. Collected data indicated that the catalytic efficiency of [RuIV(TPP)(OCH[Formula: see text]]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)(OCH[Formula: see text]]2O with Ph3CN3 or (CH[Formula: see text]SiN3 afforded [RuIV(TPP)(N[Formula: see text]]2O which was fully characterised, its molecular structure was also determined by single crystal X-ray analysis.
