摘要

The reaction of ferrocene-containing alkenes and alkynes with HSi(OEt)₃ and HSiMe(OMe)₂ in the presence of Karstedt catalyst (Pt₂[(Me₂SiCH=CH₂)₂O]₃) was studied. It was found that only terminal alkenes underwent hydrosilylation, while alkynes entered this reaction even in the case of a disubstituted C≡C bond. The synthesized silicon-containing ferrocene derivatives were used as precursors for the preparation of siloxane aerogels, which were characterized by low-temperature nitrogen adsorption, scanning electron microscopy, and Mössbauer spectroscopy.
