A series of new stannylated derivatives of dimethylaminomethylferrocene (DMAMF) ans N,N-dimethylbenzylamine have been synthesised and their structures investigated by 1H, 13C and 119Sn NMR together with 57Fe and 119Sn Moessbauer spectroscopy.Polystannylated derivatives were synthesised from DMAMF and BuLi in the presence of TMED.The methylene protons of the Ch2NMe2 group were diastereotopic for all the DMAMF derivatives synthesised.The chemical shift differences of these protons is discussed in terms of conformational changes. 13C and 119Sn shifts were used to establish the substitution patterns in the polystannylated derivatives. 13C shifts for the 2-substituted derivatives of both DMBA and DMAMF were resonably additive, for both the free amines and the quaternary ammonium salts.The Moessbauer data show no evidence of pentacoordination in any of the derivatives.
