| 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 (d -p interaction) mechanisms. The effect of d-p interaction in the Si-ring bond is absent for Si(OC2H5) and SiF3 substituents.See 1] for communication III.Translated from Khimiya Geterotsiklicheskikh Soedinenli, No. 11, pp. 1483–1488, November, 1972. |
