Ferrocene derivatives. 23. Isocyanoferrocene and isothiocyanatoferrocene
Aminoferrocene has been converted into formamidoferrocene, which exists in solution as an equilibrium mixture of two rotational isomers, a monomeric cis form and a dimeric (or oligomeric) trans form. Variable-temperature 1H and 13C{1H} NMR spectra have been used to measure ΔG for the hindered internal rotation about the C-N bond. Dehydration of formamidoferrocene yields isocyanoferrocene, which has been characterized by complex formation with iron and molybdenum carbonyls. A high-yield conversion of aminoferrocene into isothiocyanatoferrocene is described.
