A synthesis and isolation method for α-benzoin oxime was reported. With benzaldehyde as starting material and dicationic imidazolium salt as catalyst, α-benzoin as an important intermediate was synthesized through the mechanism of nitrogen heterocyclic carbine. This method is characterized by mild conditions, low cost, environment friendly and good yield. In the α-benzoin oximation reaction, adjusting the reaction temperature can get selective control of oxime structure for cis-trans isomers which were completely separated by column chromatography using gradient elution.

Key words: α-benzoin oxime, synthesis, cis-trans isomer, separation
