実験手順

2 g (14 mmol) of 1-methylnaphthalene in 2 ml of tributylphosphate was allowed to react with electrochemically produced Ag(II) sulphate at 23° C. The electrolyte solution was composed of 0.02M Ag(I) sulphate in 1.5M H2SO4. The reaction was run for 26 hours at 200 mA. The organic material isolated from the run was placed on a silica gel column, which was eluted with petroleum ether (bp=60°-80° C.) then with a solution of 1% ether in petroleum ether. From this column there were obtained 1.2 g (8.4 mmol, 60%) of starting material and 92 mg (0.32 mmol, 4.6%) of 4,4'-dimethylbinaphthyl.
