摘要：
The phenylselenenyl sulfate, generated from the oxidation of diphenyl diselenide with ammonium persulfate, easily effects electrophilic aromatic substitution reactions on thiophene, 2-and 3-methylthiophenes and on 3-bromothiophene. The phenylseleno group activates the substrate to further substitution. Under controlled experimental conditions, it is thus possible to introduce the desired number of phenylseleno groups into the thiophene ring.
