Meta- or para-nitro-(pentafluorosulfonyl)benzenes underwent the Davis reaction with arylacetonitriles to provide the SF5-containing benzisoxazoles. Good yields were obtained with arylacetonitriles containing the electron-neutral or electron-donor group, while those with the electron-acceptor group were found to be unreactive. Reductions of the benzisoxazoles gave ortho-aminobenzophenones in high yields. Their synthetic utility was demonstrated by condensation reactions with carbonyl compounds or amines to provide SF5-containing quinolines and quinazolines, respectively.
Meta-或para-硝基-(五氟磺酰基)苯经过与芳基乙腈的Davis反应,生成含SF5基团的苯并异噁唑。对电子中性或电子供体基团的芳基乙腈获得了良好的产率,而对于带有电子受体基团的芳基乙腈则发现其不活泼。苯并异噁唑的还原反应可以高产率地生成邻氨基苯苯酮。它们的合成效用通过与羰基化合物或胺的缩合反应得到了展示,分别提供了含SF5基团的喹啉和喹唑啉。
