Reaktionsschritte

4.28 g (20 mmol) of sodium 1-naphthalenesulfinate, 4.14 g (20 mmol) of 1-bromonaphthalene, 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 12.8 mmol (yield 64%) of 1,1'-binaphthyl was formed in the reaction mixture solution.
