摘要

1-Aryl-2, 2-dichloro-7, 1-aryl-2, 2-dibromo-8, 1-aryl-2-bromo-2-fluoro-9 and 1-aryl-2-chloro-2- fluoro-ethanone oximes 10 have been prepared by allowing the corresponding ketones to react with hydroxylamine hydrochloride in EtOH at room temperature. Stereochemical assignments for the oximes were made on the basis of 1H NMR spectroscopic evidence and an X-ray crystallographic analysis of 1-(3-chlorophenyl)-2, 2-dichloroethanone oxime 7f. ...
