the mechanism of amination reactions of ethylbezene catalyzed by ruthenium porphyrin complexes

Transition metal-catalyzed nitrene transfer reactions are of great interest for the formation of new C-N covalent such as alkene aziridination, C–H amidation, and sulfimidation reactions. The metal-nitrene/imide intermediates (M=NR) are supposed to be the key intermediates involved in nitrene transfer reactions.To better understand the mechanism of C-N bond formation, we performed detailed DFT study on the catalytic amination of ethylbenzene and cychohexdiene; and aziridination of styrene through ruthenium mono-imide and bis-imide porphyrin complexes.
