Quinones and quinone methides. VIII. Oxidation products of the screwworm chemosterilant, 2,4-Bis(1,1-dimethylethyl)-6-(4-methoxyphenylmethyl)phenol

Abstract

The title compound is oxidized by silver oxide in acetone to a complex mixture of products, including the benzophenone derivative (7), a benzylic alcohol, isolated as its methyl ether (15), and two spiro cyclohexadienone benzopyran dimers (17) and (19). A colourless dimer was shown by single-crystal X-ray diffraction measurements to be a 2,3- dihydrobenzofuran derivative (22).
