実験手順

0.934 g (4.40 mmol) of (1S,2S)-(-)-1,2-diphenylethylenediamine of α!D20 =-103.1° (c 1.00, MeOH ) and 1.00 g (4.40 mmol) of dl-1-hydroxy-2-hydroxyimino-1,2-diphenylethane were added to 3 ml of benzene and then heated and stirred, and the solution was cooled to room temperature. Afterward, the precipitated crystals were collected by filtration and then recrystallized from 2 ml of benzene once to obtain 0.250 g of (1S,2S)-(-)-1,2-diphenylethylenediamine·1-hydroxy-2-hydroxyimino-1,2-diphenylethane. Physical properties of the product are as follows.
