The products resulting from condensation of veratrole and α,β‐unsaturated acids in polyphosphoric acid are the corresponding 1‐indanones. With pyrogallol trimethyl ether and with resorcinol dimethyl ether the nature of the products of these condensations varies according to the α,β‐unsaturated acid employed. Usually it will be a phenyl vinyl ketone, which agrees with the results given in the literature for the reaction with anisole. The ability of the various aromatic ethers to form indanones by this condensation is discussed on the basis of the π‐electron density in the different positions of the aromatic ethers.
