Abstract

The IR spectra of organosilicon derivatives of thiophene were investigated. A comparison of the results with the literature data made it possible to isolate the characteristic absorption bands of the substituted thiophene ring and to reveal some regularities in the IR spectra of thienylsilanes. Theσ inductive constants of substituted thienyl groups
were calculated from the experimentalΝ(Si-Cl) values. An analysis of theσ values shows that electron-donor substituents X lower the acceptor capacity of the thienyl substituent as a whole, while electron-acceptor substituents increase it.
