摘要: Abstract 57 Fe and 119 Sn Mossbauer data are reported for mono- bis-triorganostannyl ferrocenes together with NMR chemical shifts. The reactions of bis-triphenyl-stannylferrocene Fc(SnPh 3 ) 2 various electrophiles have been studied. Acid cleavage occurred both FcSn PhSn bond fission. In contrast, mercuri-destannylation HgCl gave only Fc(HgCl) . Iodination a mixture the bis-iodides )(SnPh I) resulting from dominant cleavage. Oxidation by FeCl required more than one equivalent oxidant. spectra resultant ferrocinium ion was notable appearance measurable quadrupole splitting in cases; this is discussed terms polar steric effects.
