A metal-free trifluoromethylation of hydrazones with Togni’s reagent under mild conditions was developed. Various functional groups including ester, methoxy, dimethoxy, nitro, halogen, and heterocyclic compounds were tolerated. This simple and green strategy provides a practical tool to construct C(sp3)–CF3 bonds.
开发了在温和条件下用Togni试剂对进行的无金属三氟甲基化反应。容许各种官能团,包括酯,甲氧基,二甲氧基,硝基,卤素和杂环化合物。这种简单而绿色的策略提供了构建C(sp 3)–CF 3键的实用工具。
