Lead tetraacetate oxidation of N-aminophthalimide (11) in inert solvents gives as major products phthalimide (15) or trans-1,4-bisphthaloyl-2-tetrazene (12), the former (15) on slow, the latter (12) on fast addition of the oxidizing agent. As by-products are found: (a) in the presence of acetic acid: N-acetylamino-phthalimide (14), and (b) in its absence (especially at higher temperatures): benzocyclobutenedione
N-氨基邻苯二甲酰亚胺(11)在惰性溶剂中的四乙酸铅氧化得到主要产物邻苯二甲酰亚胺(15)或反式1,4-双邻苯二甲酰基-2-四氮烯(12),前者(15)缓慢,后者(12)快速添加氧化剂。发现了以下副产物:(a)在乙酸存在下:N-乙酰氨基邻苯二甲酰亚胺(14),和(b)在不存在乙酸下(尤其是在较高温度下):苯并环丁烯二酮(13)和N-邻苯二甲酰亚胺基-邻苯二甲酰亚胺(16)以及痕量邻苯二甲酸酐(17)。
