Photochemistry studies of matrix isolated carbonyl iron silyl complexes byFT-IR spectroscopy

Carbonyl iron silyl complexes of the type Cp(CO)(2)Fe-SiH2R (Cp = cyclopent adienyl) (R = H (1), Me (2)) were subject to a very interesting photochemis try. They were isolated in krypton matrices and subsequently detected by FT -IR spectroscopy. To study the photochemistry of these complexes, IR spectr a were taken after UV irradiation. As a result of the observed differences in the spectra, the reaction mechanism for the photochemical conversion of these compounds, which we postulated on the basis of Raman measurements ear lier, is now confirmed.
