✦ Synopsis

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.
