反应详情

In a hydrogenation reactor, 1 g of 2-(2-nitrophenyl)-bicyclopropane (4.9 mmol, trans:cis ratio: 4.1:1), dissolved in 20 ml of ethanol, is hydrogenated at ambient temperature using 0.1 g of 5% platinum-carbon catalyst. After 2.5 hours and after 101% of the amount of hydrogen theoretically required for the reduction has been taken up, the reaction is stopped. Following filtration of the reaction mixture, the solvent is removed by concentration by evaporation. 0.87 g of 2-(2-aminophenyl)-bicyclopropane (100% of theory) is obtained in the form of a brownish liquid (trans:cis ratio: 4.4:1).
