Description

The products of O-protonation of metallocenecarbaldehydes C5Me5MC5Me4CHO (M = Fe, Ru, Os) with HBF4 and CF3COOH were prepared for the first time and adducts [C5Me5MC5Me4CH(OH)]+BF- were isolated. It was shown that structures depend on the nature of the metal and anion. For Ru and Os adducts the competition of metal atom and anion for the formation of H-bond with OH-group. They give the cyclic structure with intramolecular hydrogen bond M...OH in the presence of basic anion BF4-. Structure of adducts were confirmed by IR and 1H NMR spectra, the structure was proved by X-ray diffraction analysis for (C5Me5RuC5Me4CHOH)+...F-. 17 refs., 2 figs., 4 schemes, 5 tabs
