Decarboxylative Cleavage During Friedel-Crafts Reaction of 3,3-Diarylpentanedioic Anhydride with Anisole

Korgaonkar, U. V.,Samant, S. D.,Deodhar, K. D.,Kulkarni, R. A.

, p. 572 - 574 (2007/10/02)

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.
