Regioselectivity of the allylation of benzothiophene

Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The reaction of benzothiophene with allyl halides in the presence of silver trichloroacetate in chlorine-containing hydrocarbons was investigated. It was established by gas-liquid chromatography and 13C NMR and mass spectrometry that 3-allylbenzothiophene and diallylbenzothiophene are formed in this case. The 13C NMR spectra were interpreted on the basis of an additive scheme with the utilization of benzothiophene, thiophene, and 2- and 3-allylthiophenes as models.
