A new ferrocene-containing charge-transfer salt, (TTF) [Fe(C H -CH(CH )NHCOCH SO ) ]

A novel ferrocene-containing dianion, Fe(C H - CH(CH )NHCOCH SO ) (1), has been prepared. The oxidation potential of the PPh salt is + 0.35 V (vs. SCE in PhCN), indicating that it is a stronger donor than TTF (tetrathiafulvalene) by + 0.03 V. The dianion provided a TTF salt, the structure and physical properties of which are reported. © 2012 Elsevier B.V. All rights reserved.
