Treatment of acetonedicarboxylic acid with excess aryl ethers gives 3,3-diarylpentanedioic acids in good yields. 3,3-Diarylpentanedioic anhydrides (VII) on the Friedel-Crafts reaction with aryl ethers in the presence of AlCl3 in nitrobenzene give a mixture of 3,3-diarylpropenoic acids (X) and 1,1-diarylethenes (IX) instead of the normal product, 3,3-diaryl-4-aroylbutanoic acid.
