Preparation and molecular structure of [(η 5-C 5H 5)Fe(CO) 2(η 1-PhNO 2)]BF 4

Abstract

The nitrobenzene complex [(η 5-C 5H 5)Fe(CO) 2(PhNO 2)]BF 4 ( 1) has been prepared by the reaction of CpFe(CO) 2I with AgBF 4 in the presence of nitrobenzene. Characterization by X-ray diffraction reveals that complex 1·1/2(CH 2Cl 2) has a nearly planar PhNO 2 ligand coordinated in the η 1-O mode. Reactivity studies indicate that 1 is not a primary intermediate in the allylic amination of olefins by nitroarenes which are catalyzed by [CpFe(CO) 2] 2.
