Participants

Reaction Conditions

Reaction Steps

101.4 g of triphenylamine and 35.5 mL of dimethyl formamide (DMF) were placed in a three-neck flask, and while stirring with cooling in ice water, 84.4 mL of phosphorus oxychloride was dropped into the flask. The temperature was raised to 95° C., and the mixture was reacted for 5 hours. The reaction solution was poured into 4 L of warm water and stirred for 1 hour. The precipitate was then collected and washed in a 1:1 mixture solution of ethanol/water, and 4-(N,N-diphenylamino) benzaldehyde was obtained. The yield was 91.5 g (yield rate of 81.0%).
