Conclusions

  1. 1.

    The IR and UV spectra of (2-organylsulfinylethyl)trifluorosilanes indicate the existence of a strong intramolecular coordination bond of the silicon atom with the sulfoxide group oxygen atom. In benzene, dipole measurements show that these compounds are capable of self-aggregation.

     
  2. 2.

    The molecular ions of (2-organylsulfinylethyl)trifluorosilanes formed upon electron impact may exist in two forms: with and without an intramolecular Si ← O coordination bond. The decomposition of the ion with the pentacoordinated silicon atom proceeds with the formation of the [M-F]+ ion, while the decomposition of the noncoordinated ion form is typical for dialkyl sulfoxides.
