Photolysis of a series of acridine 10-oxides (Ia-Ig) in various solvents is reported. The structures of photo-products were determined by syntheses, chemical transformation to the known compounds, or by direct examination of their spectroscopic data. Based on the structures of photo-products and the solvent effect on the product distribution in these photolyses, a mechanistic rationalization of these photo-reactions is presented. The characteristic features of the photo-rearrangement reactions of acridine 10-oxides are discussed and compared with those of bicyclic and monocyclic azine N-oxides, e, g., quinoline 1-oxides and pyridine 1-oxides.
