Participants

Reaction Steps

In a 1-liter three-necked flask equipped with a stirring device, a thermometer and a nitrogen substituting device, 32.6 g of 1,2-bis(4-(4-nitrobenzoyl)phenyl)ethane and 200 milliliters of dichloromethane were introduced. 42.0 g of trifluoromethane sulfonic acid was added dropwise for 15 minutes. Subsequently, a solution of 40.7 g of triethylsilane in 50 milliliters of dichloromethane was added dropwise for 1 hour. After the end of the dropwise addition, stirring was carried out for 18 hours with warming to room temperature. After the end of the reaction was confirmed by a liquid chromatography, the reaction solution was neutralized with an aqueous solution of sodium carbonate and washed with water. After removing dichloromethane by a rotary evaporator, 27.6 g of 1,2-bis(4-(4-nitrobenzyl)phenyl)ethane was obtained as crystals by recrystallizing from a toluene solvent.
