| Abstract: | Investigations of the author in thiophene chemistry developed during the last four decades are reviewed. Stereochemical studies, metallation and halogen-metal exchange, spectral studies (mainly those of NMR in thiophene and related series), studies of tautomerism in hydroxythiophenes and atropisomerism in bithienyl derivatives, ring opening of 3-thienyllithium derivatives and thiophene-1,1-dioxides, as well as studies of thieno fused heteroaromatic boron compounds are considered in detail. |
