참여 물질

반응 단계

Keeping the temperature at -5° C., to a suspension of 5.0 g (0.131 moles) of LiAlH4 in 300 ml of ethyl ether, 35 g (0.168 moles) is added of 3-phenyl-1-indanone dissolved in 50 ml of THF. The oil obtained by evaporating ether (40 g), is dissolved in 300 ml of toluene containing 20 g of Sio2 and kept refluxing for 2 hours, with formed water being distilled off. The resulting mixture is filtered, the solvent is evaporated and by distillation 18 g is obtained (yield of 50%) of 1-phenylindene boiling at 95-100° C./0.2 mm Hg.
