YieldReaction ConditionsOperation in experiment
59% With titanium tetrachloride; In dichloromethane; at 20℃; for 0.25h; Dichloromethyl methyl ether (1.2g, 10.4 mmol) was added to a stirred solution of 2,7-di-tert-butylpyrene 1 (2.4g, 7.6 mmol) in dichloromethane (200 mL). Titanium tetrachloride (5.0 mL, 46 mmol) was then carefully added to the solution; the mixture was then stirred for 15 min at room temperature. Next, the solution was poured into water, the organic layer was washed with water, dried over anhydrous magnesium sulfate, and filtered. The filtrate was evaporated under reduced pressure to obtain a residue, which was washed with hexane to give 2,7-di-tert-butyl-4-formylpyrene 2 as yellow powder (1.54 g, 59percent).
