Carbazole → 9-Phenylcarbazole

Participants

Reaction Conditions

Reaction Steps

2.5 g of carbazole, 2 g of bromobenzene and 0.064 g of a palladium acetate catalyst were dissolved in 40 mL of toluene, and the resulting solution was heated to 60° C. Subsequently, a solution of 1.5 g of sodium butoxide and 0.385 g of tri-tert-butylphosphine dissolved in toluene was slowly added dropwise. The mixture was refluxed at a steady 100° C. After completion of the reaction, the reaction mixture was extracted with dichloromethane and distilled water, and the solvent was dried. The resulting solid was filtered and purified, yielding a 9-phenyl carbazole compound as an intermediate.
