Bis-acyl derivatives of diphenyl sulfide and diphenyl ether were synthesized by successive Friedel-Crafts acylations with 2-bromo-2-methylpropanoyl bromide and acetyl chloride. The subsequent reaction with sodium p-toluenesulfinate afforded the corresponding sulfones, and condensation of the latter with benzaldehyde in acetic acid in the presence of perchloric acid gave pyrylium salts with a beta-ketosulfonyl fragment in the side chain.
