Abstract Perylene‐3,4‐dicarboxylic anhydride ( 3 ) is prepared from technical grade perylene‐3,4:9,10‐tetracarboxylic anhydride ( 1 ) in 25% yield by a partial decarboxylation reaction using noncondensing amines. Perylene‐3‐carboxylic acid ( 4 ) and perylene‐3,4‐dicarboxylic imide ( 5 ) are prepared in the same way in yields of 24% and 76%, respectively, by a variation of the reaction conditions.
