The chemistry of thiophene S-oxides1 and related compounds

Abstract

The synthesis and reactivity of thiophene S-oxides is discussed, with special emphasis on the use of thiophene S-oxides as dienes in Diels-Alder type reactions, on the photochemistry and on the electrochemistry of the molecules. Where useful, the reactivity is compared to that of benzo[b]thiophene S-oxides, dibenzothiophene S-oxides, and tetracyclones.
