57Fe and 119Sn Moessbauer data are reported for mono- and bis-triorganostannyl ferrocenes together with 119Sn NMR chemical shifts.The reactions of bis-triphenyl-stannylferrocene Fc(SnPh3)2 with various electrophiles have been studied.Acid cleavage occured with both Fc-Sn and Ph-Sn bond fission.In contrast, mercuridestannylation with HgCl2 gave only Fc(HgCl)2.Iodination gave a mixture of the mono- and bis-iodides Fc(SnPh3)(SnPh2I) and Fc(SnPh2I)2 resulting from dominant Ph-Sn cleavage.Oxidation of Fc(SnPh3)2 by FeCl3 required more than one equivalent of oxidant.The 57Fe and 119Sn Moessbauer spectra of the resultant ferrocinium ion was notable for the appearance of a measurable quadrupole splitting in both cases; this is discussed in terms of polar and steric effects.
