On oxidation with thallium(III) nitrate in methanol, 1,3-diphenyl-1,3-propanediones 1 rearrange to give 3-oxo-2,3-diphenylpropanoic esters 2 and products derived therefrom.However, 1-(2-hydroxyphenyl)-3-phenyl-1,3-propanediones 1h-k undergo oxidative cyclization to 2-aroyl-3(2H)-benzofuranones 5.The alkali and acid catalysed cleavage of 5 is discussed.
