An efficient approach to α,β-unsaturated a'-iodo ketones directly from α,β-unsaturated ketones by selective iodination at the a'-position, without effect on the double bond and the activated benzene ring, in the presence of copper(II) oxide/iodine is described. The present method has the advantages of high yields, short reaction times, inexpensive reagents, mild reaction conditions, ease of manipulation
在铜存在下,通过在 a'-位选择性碘化直接从 α,β-不饱和酮生成 α,β-不饱和 a'-碘酮的有效方法,对双键和活化苯环没有影响( II) 描述了氧化物/碘。本方法具有收率高、反应时间短、试剂便宜、反应条件温和、易于操作、产物清洁等优点。
