YieldReaction ConditionsOperation in experiment
93% With formamide In neat (no solvent) for 0.333333 h; Milling; Heating; Green chemistry General procedure: A mixture of anhydride (1 mmol), formamide (1.1 mmol for monoanhydrides and 2.2 mmol for dianhydrides) and 1 g clay was ground together in a mortar using pestle for the time described in Table 1. The reaction mixture was warmed. After completing the reaction (monitored by TLC, after observing no anhydride presence in the reaction mixture), the product was extracted by washing clay with chloroform (2×15 mL), the solvent was removed under vacuum to afford the relevant N-unsubstituted cyclic imide. The solid imide was washed thoroughly with water, dried, and then recrystallized from ethanol. The solid clay portion was washed with methanol and dried at 120 °C under a reduced pressure to be reused in the subsequent reactions which showed the gradual decrease in the activity (Table 1). Isolated products were characterized by melting points, IR, 1H NMR spectrometric data and were compared with the literature or authentic samples.

YieldReaction ConditionsOperation in experiment
75% With oxygen In acetonitrile at 20℃; for 24 h; The electron transfer reaction from the cyanide anion to1,2-dicarbonyl compounds and their monoimine derivatives1a–f was performed under stirring conditions in dryacetonitrile (40 mL) solutions where the substrate(0,25 mmol) was maintained for 24 h (48 h for 1a and1e) at room temperature and usual laboratory illumina-tion conditions, in the presence of sodium cyanide(10 mmol) over an open-air vessel. The reaction wasfollowed by TLC until complete disappearance of thestarting compound.
