Conclusions

  1. 1.

    According to IR spectroscopic data, (acylthiomethyl)trifluorosilanes in the solid state and in solutions exist in the form of an equilibrium mixture of isomers with tetra- and pentacoordinated Si atoms.

     
  2. 2.

    (Acylthiomethyl)trifluorosilanes with intramolecular and intermolecular Si ← 0 coordination bonds are characterized by a higher degree of dipole-dipole interaction with the medium in comparison with (aroyloxymethyl)trifluorosilanes.

     
  3. 3.

    (Acylthiomethyl)trifluorosilanes containing a tetrahedral Si atom consist of a mixture of rotational isomers around the =C-S bond.

     
  4. 4.

    The thermodynamic parameters of isomerism have been determined for the gaseous state of the compounds.
