Extended Pummerer reaction of arylketene dithioacetal monoxides with aromatic compounds by means of trifluoromethanesulfonic anhydride proceeded in moderate to good yields. In the case of intramolecular cyclization of (2-arylphenyl)ketene dithioacetal monoxides, phenanthrenes were obtained via ring-closure and skeletal rearrangement.
