title: Spectroelectrochemical investigation of Bu4N[Fe(CO)3(NO)]: identification of a reversible EC-mechanism.
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%.
