PREPARATION OF SUBSTITUTED PHTHALIC ANHYDRIDE, ESPECIALLY 4-CHLOROPHTALIC ANHYDRIDE

A method for the synthesis of substituted phthalic anhydrides (IV) wherein R' is a halogen, aromatic or aliphatic group comprising 1-18 carbons, hydrogen or nitro group is the transimidation between a substituted N-alkyl phthalimide (V) wherein R is an alkyl having from 1 to 18 carbons, and a substituted tetrahydrophthalic anhydride (VI): The by product of this reaction, a substituted N-alkyl tetrahydrophthalimide (VII), may be converted by aromatization to the substituted N-alkyl phthalimide (V).
