Conclusions

  1. 1.

    A scheme for the evaluation of the pπ-dπ conjugation based on the comparison of data from photoelectron spectroscopy and the results of quantum-chemical calculations in the framework of Koopman's theorem has been proposed, and evaluations of the σ-π, inductive, and pπ-dπ effects in several organosilicon derivatives of ethylene and furan have been carried out.

  2. 2.

    The influence of organosilicon substituents on the energy of π MOs in comparison to that of the isostructural carbon substituents in the absence of conjugation is consistent with the theory of electronegativity.

  3. 3.

    The Taft inductive constants have been determined for the first time for eight organosilicon substituents.
