• The photochemical reactions of <I>N</I>-acetyl diphenylamine and <I>N</I>-acetyl carbazole in solution have been studied. <I>N</I>-Acetyl diphenylamine and <I>N</I>-acetyl carbazole undergo the photo-Fries-rearrangement by means of 2537Å irradiation. The reaction products consist of the <I>ortho</I>- and <I>para</I>-isomers, plus corresponding amines transformed through the deacetylation of the original compounds. The quantum yields in the early stages of the rearrangement were measured under various conditions by spectrophotometry. The reaction mechanism has been discussed on the basis of the relation between the rate constants of the rearrangement and the odd π electron densities obtained from simple Hückel MO calculations.
