1,2-Dibromobenzene → O-Terphenyl

Participants

Reaction Steps

3.28 g (20 mmol) of sodium benzenesulfinate, 2.36 g (10 mmol) of o-dibromobenzene, 0.0255 g (0.1 mmol) of palladium acetate, 0.0478 g (0.12 mmol) of 1,2-bis(diphenylphosphino)-ethane, 6.73 g (120 mmol) of calcium oxide and 60 ml of N-methyl-2-pyrrolidone were placed in a 100 ml round bottom flask and reacted at 150° C. in a nitrogen gas stream for 8 hours. After the completion of the reaction, the reaction mixture was analyzed by means of high performance liquid chromatography. The analysis showed that 4.5 mmol (yield 45%) of o-terphenyl was formed in the reaction mixture solution.
