The oxidation of thiophenes by peracids to form thiophene S-oxides could not be carried out with benzothiophenes.With the sterically hindered compound 1a the quinones 2 and 3 were produced whereas the anisyl-substituted derivative 1b formed the sulfine 5.Significantly different behavior of 1a and 1b was also observed for the Diels-Alder reaction with N-phenylmaleimide.The unexpected and unusual adduct 6 was the only product formed from 1a, with low yield though, whereas the normal Diels-Alder adduct was obtained from 1b.
