Abstract

Bu₄N[Fe(CO)₃(NO)] displays unique catalytic properties in electron-transfer catalysis such as in allylic substitutions, hydrosilylation, transesterifications, or carbene transfer chemistry. Herein we present a detailed spectroelectrochemical investigation of this complex that unravels an interesting electrochemical-chemical transformation in which two parts of [Fe(CO)₃(NO)]^- are oxidized and undergo a disproportionation in the presence of CO to [Fe(CO)₅] and [Fe(CO)₂(NO)₂]. Upon re-reduction the former two complexes regenerate [Fe(CO)₃(NO)]^- to about 85%.
