Abstract

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