Pentacoordinate silicon compounds containing a "chelate" six-membered silacarbofunctional ring, such as the chloro-dimethylsilanes, with R=CF3 (Ib), C6H5 (Ic), 4'-MeC6H4 (Id), 4'-MeOC6H4 (Ie) 4'-NO2C6H4 (If) have been synthesized for the first time and were studied by NMR spectroscopy.In contrast to Ib in molecules of Ia (R=Me), Ic-If the Cl-Si bond rather than O-Si bond is the weaker component of the hypervalent O-Si-Cl bond, which implies the possibility of Cl->Si coordinative interaction.An irreversible rearrangement of compounds I upon heating leads to (O-Si)chlorodimethylsilanes, (II), and was used for preparative purposes.
