Abstract:
1. A process for preparing 2-tert-butyl-9,10-bis-(β-naphthyl)anthracene comprising: reacting 2-bromonaphthalene with a metal while a reaction temperature is increased from −78° C. to room temperature to yield a naphthyllithium compound; cooling the reaction to −78° C. and adding 2-tert-butylanthraquinone to the reaction; reacting the naphthyllithium compound with the 2-tert-butylanthraquinone while the reaction temperature is increased from −78° C. to room temperature to yield a diol; reacting the diol with a reducing agent in a dioxane at 50° C. to yield the 2-tert-butyl-9-10-bis-(β-naphthyl)anthracene; and drying and purifying the 2-tert-butyl-9-10-bis-(β-naphthyl)anthracene by Kaufman column and sublimation at 320° C., wherein the reducing agent is vanadous chloride in an acid and with water.
