4-Bromotoluene → Di-p-tolyl

Participants

Reaction Steps

3.56 g (20 mmol) of sodium p-toluenesulfinate, 3.42 g (20 mmol) of p-bromotoluene, 0.0225 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 17.1 mmol (yield: 86%) of 4,4'-dimethylbiphenyl was formed in the reaction mixture solution.
