Abstract:
According to the data of quantum chemical calculations (HF, DFT), the isolated sp,sp conformer of (acetoxymethyl)trifluorosilane — pentacoordinated silicon compound — forms dimers with two intermolecular bonds Si-F→Si. The =O→Si intramolecular coordination bonds become stronger, which leads to the general stabilizing effect. In polar media, dimer formation is energetically unfavorable relative to monomer formation.
