Triphos-Fe dinitrogen and dinitrogen-hydride complexes: relevance to catalytic N reductions.

Laboratoire Hétérochimie Fondamentale et Appliquée, Université Paul Sabatier, CNRS, 118 Route de Narbonne, 31062 Toulouse, France.

Published: October 2018

The two electron reduction of iron complexes [(PP)Fe(Cl)] (R = Ph or tBu) 2a-b afforded complexes [(PP)Fe(N)] 4a-b. Protonation of 4a at the metal center and subsequent reduction to Fe(i)-H species lead to complex [(PP)Fe(N)(H)] 6avia a spontaneous disproportionation reaction. Complex 4a behaves as one of the most efficient monometallic Fe-catalysts reported to date for N-to-N(SiMe) functionalization under atmospheric pressure.
