    Description / Table of Contents: Oxidation of 1,3-Diphenyl-1,3-propanediones with Thallium(III) Nitrate in MethanolOn 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.
    Notes: Bei der Oxidation mit Thallium(III)-nitrat in Methanol werden die 1,3-Diphenyl-1,3-propandione 1 zu den 3-Oxo-2,3-diphenylpropansäureestern 2 und deren Folgeprodukte umgelagert. Die 1-(2-Hydroxyphenyl)-3-phenyl-1,3-propandione 1h-k werden dagegen oxidativ zu den 2-Aroyl-3(2H)-benzofuranonen 5 cyclisiert.  -  Der durch Alkalilauge und Säure katalysierte Abbau von 5 wird diskutiert.
