9-Bromophenanthrene → N-(Phenanthren-9-yl)phenanthren-9-amine

Participants

Reaction Steps

9-bromophenanthrene (7.00 g, 27.22 mmol), phenanthren-9-amine (5.26 g, 27.22 mmol), Pd2(dba)3 (499 mg, 0.544 mmol), tris-t-butylphosphine (0.123 mL, 0.544 mmol), sodium tert-butoxide (3.90 mg, 40.84 mmol) were put in a 250 mL two-neck flask and dissolved in toluene. The solution was refluxed and stirred for 12 hours. After completion of the reaction, the solution was extracted with DI water/methylenechloride and distilled under reduced pressure to remove the solvent. The resultant was columned with a solution of n-hexane and methylenechloride (3:1) and was re-crystallized in a solution of methylene chloride and petroleum ether such that the solid compound was obtained, (4.50 g, yield: 45%).
