Zusammenfassung:	The invention relates to a process for the preparation of phenol which comprises the aerobic oxidation of cumene to hydroperoxide with high conversions and selectivities, in the presence of new catalytic systems, extremely mild conditions and the subsequent acid decomposition of the hydroperoxide to phenol and acetone. L'invention concerne un procédé de préparation de phénol, comprenant l'oxydation aérobique de cumène en hydroperoxyde avec des conversions et des sélectivités élevées, en présence de nouveaux systèmes catalytiques et de conditions extrêmement douces, et la décomposition acide ultérieure de l'hydroperoxyde en phénol et acétone.
