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).
一种合成取代邻苯二酐(IV)的方法,其中R'是卤素,芳香基或脂肪基,包括1-18个碳,氢或硝基,通过取代N-烷基邻苯二
酰亚胺(V)(其中R是具有1至18个碳的烷基),和取代四氢邻苯二酐(VI)之间的转酰胺反应合成:该反应的副产物为取代N-烷基四氢邻苯二
酰亚胺(VII),可以通过芳香化反应转化为取代N-烷基邻苯二
酰亚胺(V)。
