Abstract:
Radical ideas : Reaction of the iron(IV) nitrido complex PhB(MesIm)3Fe?N] (see picture, Mes=2,4,6‐Me3C6H2) with TEMPO‐H (1‐hydroxy‐2,2,6,6‐tetramethylpiperidine) results in high yields of ammonia and quantitative formation of PhB(MesIm)3Fe(tempo)]. The mechanism likely involves hydrogen‐atom transfer from TEMPO‐H to the nitrido complex. Similar reaction with the triphenylmethyl radical yields PhB(MesIm)3Fe?N? CPh3].
