(4) and (5) reacted mildly with aromatic compounds in the presence of Lewis acids to give the corresponding sulfides which in turn desulfurized to arylmethylene ketones, arylacetoesters, and arylacetonitriles.
Lewis acid-promoted reactions of arenes with α-chloro-α-(methylthio)acetophenones 6-8 gave the Friedal-Crafts reaction products 9, which were then treated with 3 molar eq of cupric chloride in aqueous acetone to afford the unsymmetrically substituted benzils 10.
