摘要: Abstract 57Fe-NMR spectra (16.1 MHz; natural abundance) of mono- and 1,1′-disubstituted ferrocene derivatives (1–15), including two ferrocenophanes (14, 15), could be measured in a much shorter time than expected according to previous reports (500 MHz spectrometer, standard equipment; solutions 5-mm tubes). Substituents were tBu, alkynyl, silyl, germyl, stannyl boryl groups, the bridges SiMe2 (14) Me2SiSiMe2 units (15). The δ57Fe values cover fairly large range >450 ppm. There is difference (365 ppm) 57Fe nuclear shielding for ferrocenophanes, with higher [1]ferrocenophane 14. Parallel trends observed between δ55Mn comparable sandwich complexes derived from [(η5-C5H5)Mn(η6-C6H6)].
