Here, we report an efficient and modular approach toward the formation of difluorinated arylethylamines from simple aldehyde-derived N,N-dialkylhydrazones and trifluoromethylarenes (CF3-arenes). This method relies on selective C–F bond cleavage via reduction of the CF3-arene. We show that a diverse set of CF3-arenes and CF3-heteroarenes react smoothly with a range of aryl and alkyl hydrazones. The β-difluorobenzylic
在这里,我们报告了一种从简单的醛衍生N,N -二烷基腙和三氟甲基芳烃 (CF 3 -芳烃)形成二氟化芳基乙胺的有效模块化方法。该方法依赖于通过 CF 3 -芳烃的还原选择性 C-F 键断裂。我们表明,一组不同的 CF 3 -芳烃和 CF 3 -杂芳烃与一系列芳基和烷基腙顺利反应。β-二氟苄基肼产物可以选择性地裂解形成相应的苄基二氟芳基乙胺。
