Reactivity of three-coordinate iron-NHC complexes towards phenylselenol and lithium phenylselenide

Abstract

The three-coordinate iron(ii) NHC complexes [(IPr)Fe(N′′) 2] (1) and [(ItBu)Fe(N′′)2] (3) (N′′ = N(SiMe3)2) react with PhSeH or LiSePh to give the iron(ii) selenolates [(IPr)Fe(N′′)(SePh)] (6) and [ItBu(H)][(aItBu)Fe(SePh)3], [I tBu(H)][7], with complex 7 containing an abnormal NHC ligand. © 2014 The Royal Society of Chemistry.
