Reports of direct C–H N-functionalization of arenes lacking activating/directing groups, however, are sparse and limited in substrate and N-reagent scope. 8 The direct conversion of benzene to aniline using redox active transition metal oxides with NH 3 /O 2 or hydroxylamine as N-reagents proceeds with moderate efficiency, but its substrate scope is unknown. 9 Transition metal-promoted arene amination by PhI NTs has been catalyzed by: (1) AuCl 3 10 and (2) ...
