Phenyl aroylacetates were obtained by the reaction of phenols and pyrocatechol with 5-aryl-2,3-dihydrofuran-2,3-diones under conditions for the decarbonylation of the lattter. The reaction between 5-aryl-2,3-dihydrofuran-2,3-diones and salicylaldehyde and 2-hydroxynaphthaldehyde under the same conditions led to the formation of 3-aroyl-2H-chromen-2-ones, 2-(2-aroylacetoxy)phenyl-6-aryl-1,3-dioxin-4-ones, and 3-aroyl-2H-benzo(f)chromen-2-ones.The PMR spectra of the obtained solutions of the substances in acetone-d/sub 6/ were recorded on an RS-60 spectrometer at 60 MHz with HMDS as internal standard. The mass spectra were obtained on a Varian MAT-311 mass spectrometer.
