stannylated derivatives of dimethylaminomethylferrocene (DMAMF) and N,N-dimethylbenzylamine have been synthesised and their structures investigated by 1H, 13C and 119Sn NMR together with 57Fe and 119Sn Mössbauer 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
Intramolecular nucleophilic assistance at tin: reversal of selectivity in S E2 cleavage of mixed tetraorganotin compounds by iodine

Electrophilic cleavage of mixed-functionality tetraorgantin compounds by iodine reveals a complete reversal of the usually observed selectivity, i.e. alkyltin–carbon bonds are broken in preference to aryl- or vinyl-tin–carbon bonds; this unexpected result is explained by intramolecularassistance at tin.
