Under microwave irradiation, boron trifluoride has been found to mediate a new condensation reaction of aryl ketones with triethyl orthoformate to give a series of new products (Cl-C10) is described. The compounds were first reported. Their structure were determined by IR, MS, and 1H /13C NMR spectra.

During the action of an anhydrous solution of perchloric acid in alcohol on methyl aryl ketones in ethyl orthoformate open-chain carboxonium salts (derivatives of the 1,5-diaryl-2-pentene-1,5-dione) were formed instead of the 2,6-diarylpyrylium perchlorat
