One-Electron Oxidation and Protonation of Diferrocenylphenylphosphine

Corina Stoian , Serhiy Demeshko, Malte Fischer , Jens Beckmann

Abstract

The one-electron oxidation and protonation of Fc2PhP leads to the formation of two distinct, stable cationic phosphorus species, namely the radical cation [Fc2PhP][B(C6F5)4] and the phosphonium ion [Fc2PhPH][B(C6F5)4], respectively. While their solid-state structures are remarkably similar, the bathochromic shift in the UV-vis absorption spectrum of the radical cation, signals with distinct multiplicities in the 31P NMR spectra, as well as contrasting quadrupole splitting values in the 57Fe Mößbauer spectra elucidated the differences between the two cations.
