Abstract

Substituents in disubstituted thiophenes have an additive effect on the chemical shifts of the ring hydrogen atoms. The electronic effects of organosilicon substituents are transmitted via inductive and conjugation (dπ-pπ interaction) mechanisms. The effect of dπ-pπ interaction in the Si-ring bond is absent for Si(OC2H5) and SiF3 substituents.
