YieldReaction ConditionsOperation in experiment
at 20 - 100℃; for 36h; To a 50 mL round bottom flask was added 1,2,4,5-tetraaminobenzene hydrochloride 1 (284 mg), formic acid (10 mL) at room temperature. The reaction was heated to 100 C for 36 hours. Cooled to room temperature, neutralized to neutral with NaOH solution, filtered and dried. The precipitate was transferred to 50 mL standard Schlenk vials, NaH (80 mg, 60%), 5 mL of toluene, followed by heating to 110 C under nitrogen. After cooling to room temperature, 1-bromobutane (1 mL) and DMF (5 mL) were added, and the mixture was heated to 110C for 4 hours to disappear the starting material. After cooling to room temperature, the inorganic salt was removed by filtration and recrystallized from methylene chloride-methanol to give tetrabutylbenzobisimidazole bromide salt 3a. Yield: 530 mg, 98%

YieldReaction ConditionsOperation in experiment
at 100℃; for 36h; 1,2,4,5-Benzenetetraamine tetrahydrochloride (284 mg, 1.00 mmol) was poured into a round bottom flask was charged with a magnetic stir bar. 120 Formic acid (88-99%) was added and the flask was fitted with an air-jacketed condenser. The reaction carried out in an oil bath at 100 C. for 36 h. The reaction mixture was then allowed to cool, decanted into ice-cold water (equal volume to formic acid) and neutralized with K2CO3. Neutralization caused precipitation of the 121 product which was collected via vacuum filtration, washed with cold water, and dried under vacuum. The desired product as a light brown solid: 1H NMR (250 MHz, DMSO-d6, D2O) delta 7.651 (s, 2H), 8.156 (s, 2H); 13C NMR (250 MHz, DMSO-d6) delta 99.67, 135.38, 143.01. See Karimi, B. et al. Inorg. Chem., 2011, 50, 6063.
