condensation reactions. In accordance with this, boiling 2,4,6-triphenylpyrylium perchlorate (I) with acetic anhydride in the presence of sodiumacetate led to the formation of 1,3,5-triphenylbenzene (Va) [9]. We have established that the reactions of pyrylium salts with the anhydrides of acetic, propionic, and butyric acids in the presence of the corresponding sodium carboxylates led to the formation of triarylbenzenes
