Reaktionsschritte

3.56 g (20 mmol) of sodium p-toluenesulfinate, 3.74 g (20 mmol) of p-bromoanisole, 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 6 hours. After the completion of the reaction, the reaction mixture was analyzed by means of high performance liquid chromatography. The analysis showed that 15.0 mmol (yield 75%) of 4'-methoxy-4-methylbiphenyl was formed in the reaction mixture solution.
