• Photo-Fries rearrangements of <I>N</I>-acyl-2,3-dihydrobenzoxazol-2-ones are described. Irradiation of <I>N</I>-acyl-2-3-dihydrobenzoxazol-2-ones in acetonitrile afforded a mixture of 2-acyl-2,3-dihydrobenzoxazol-2-one and 6-acyl-2,3-dihydrobenzoxazol-2-one together with other minor products. However, 2,3-dihydrobenzoxazol-2-one and <I>N</I>-methyl-2,3-dihydrobenzoxazol-2-one were very photostable. The reaction scheme involving Norrish type I dissociation has been discussed.
