was investigated by voltammetry and electron paramagnetic resonance (EPR) spectroscopy methods. The reaction intermediates, such as dihydroacridine dialkylphosphonates, have been isolated, proven, and investigated by voltammetry, X-ray diffraction, etc. The magnetic resonance parameters of intermediates, the radical cations of triorganyl phosphites captured by a spin trap PBN, acridine, as well as phosphorylated
一种温和、高效的位点选择性直接 C(sp 2 ) 电化学方法)– 已开发出用亚磷酸三有机酯对吖啶进行 H 磷酸化。无催化剂、无外部氧化剂和无金属的联合电合成以良好的收率导致选择性 C9 磷酸化。通过伏安法和电子顺磁共振 (EPR) 光谱法研究了这些一锅氧化转化的机制。反应中间体,如二氢吖啶二烷基膦酸酯,已通过伏安法、X 射线衍射等方法分离、证明和研究。中间体的磁共振参数、自旋阱 PBN 捕获的亚磷酸三有机酯自由基阳离子、吖啶,以及磷酸化吖啶衍生物,已被确定。
