2-chloro-1-(2,5-dichlorophenyl)ethanone

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Cultivation, reaction and purification were carried out in the same way as described in Example 9 except that 2-chloro-1-(2', 4'-dichlorophenyl) ethanon, 2-chloro-1-(3', 4'-dichlorophenyl) ethanone, 2-chloro-1-(2', 5'-dichlorophenyl) ethanone were used as substrate, and (-)-2-chloro-1-(2', 4'-dichlorophenyl) ethanol, (-)-2-chloro-1-(3', 4'-dichlorophenyl) ethanol, (-)-2-chloro-1-(2', 5'-dichlorophenyl) ethanol was obtained. The yield, specific rotation and optical purity determined by high-performance liquid chromatography were shown in Table 6. Cultivation, reaction and purification

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
