characterization as well as with DFT-based theoretical calculations of stable dialkyl ether/poly(hydrogen fluoride) complexes are reported. Dimethyl ether/poly(hydrogen fluoride) (DMEPHF), are stable complexes of particular interest and use. The DFT calculations, that are in agreement with NMR data, suggest a cyclic poly(hydrogen fluoride) bridged structure for DMEPHF. The complex, DME-5 HF was found to be a convenient
报道了稳定二烷基醚/聚(氟化氢)配合物的制备、1H、13C 和 19F NMR 结构表征以及基于 DFT 的理论计算。二甲醚/聚(氟化氢)(DMEPHF)是特别感兴趣和使用的稳定复合物。DFT 计算与 NMR 数据一致,表明 DMEPHF 具有环状聚(氟化氢)桥接结构。发现复合物 DME-5 HF 是一种方便有效的新型氟化剂,易于处理,可应用于多种氟化反应,例如烯烃的氢氟化和溴氟化,以及醇的氟化,收率高,收率高选择性。同源二烷基醚/聚(氟化氢) (R2O/[HF]n,, R = Et,
