Low temperature activation of S8, Seredand α-Te with [CpBIGFe(CO)2] radicals

Abstract

The bulky dimeric iron complex, [(CpFe)-Fe-BIG(CO)(2)](2), readily activates elemental chalcogens (S-8, Se-red and alpha-Te) under mild conditions at room temperature. Six compounds containing Q(2)(2-) ligands (Q = S. Se) and a Te2- ligand, respectively, were isolated and completely characterized, including by X-ray diffraction techniques.
