摘要
Radical ideas: Reaction of the iron(IV) nitrido complex [PhB(MesIm) 3Fe≡N] (see picture, Mes=2,4,6-Me3C 6H2) 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]. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
