A practical variety of o-2,3,5,6-tetrafluorobenzonitrile substituted oximes ethers bearing broad functional groups were synthesized in moderate to good yields. The key highlight of this disclosure involving a one-pot two-step tandem procedure in aqueous media: the in situ formation of aryl aldehydes or ketones oximes followed by the SNAr reaction with pentafluorobenzonitrile via the high selective
一种实用的各种ö -2,3,5,6-四氟苄腈取代的肟醚轴承广泛的官能团是在中度至良好的产率合成。本发明涉及在水性介质中的单釜两步串联过程的关键亮点:原位形成芳基醛或酮肟,接着在S Ñ经由高选择性下用五氟氩反应F键裂解。
