Abstract

The iron(II) diaryl FeAr′2 (1) (Ar′ = C6H3-2,6-(C6H3-2,6-iPr2)2) reacts cleanly with O2 or CO to afford the monomeric, two-coordinate bis(aryloxide) Fe(OAr′)2 (2) or the η2-acyl–carbonyl complex (η2-Ar′C[double bond, length as m-dash]O)2Fe(CO)2 (3) viaoxygen or CO insertion into the Fe–C bonds; complex 2 has a strictly linear geometry and shows remarkable resistance to O2oxidation.
