YieldReaction ConditionsOperation in experiment
86.6% With bromine; sodium hydroxide; In 1,4-dioxane; for 5h;Cooling with ice; 3 ml of Br2 was added dropwise to a 30 ml solution of NaOH (7 g, 0.18 mol) in an ice bath.Stir for 20 min, then pour the solution into a constant pressure dropping funnel.The mixture was gradually added dropwise to a solution of 2.0 g of 4,4',4"-triacetyltriphenylamine in 1,4-dioxane (50 ml) for 5 hours at 45 C.The mixture was then subjected to an ice bath and saturated hydroxylamine HCl was added to reduce excess sodium bromide.Acidifying the solution with hydrochloric acid,The obtained solid product was filtered and dried under vacuum.Finally, the crude product is recrystallized from acetic acid.Obtaining the pure product 4,4',4"-tricarboxytriphenylamine H3TCA,It is a white solid. Yield: 86.6%.
