The stable lithium diphosphene anion radical, [Li(dme)3]+[TbtPPTbt]− (dme: 1,2-dimethoxyethane, Tbt: 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl), was readily synthesized by the one-electron reduction of the corresponding neutral diphosphene (TbtPPTbt). The molecular structure of the diphosphene anion radical was discussed in detail on the basis of its ESR, UV–Vis and Raman spectra, and theoretical
易于合成稳定的二膦酸锂阴离子基团[Li(dme)3 ] + [TbtPPTbt] -(dme:1,2-二甲氧基乙烷,Tbt:2,4,6-三[双(三甲基甲硅烷基)甲基]苯基]通过相应的中性二膦(TbtPPTbt)的单电子还原。根据其ESR,UV-Vis和拉曼光谱以及理论计算,详细讨论了二膦阴离子自由基的分子结构。发现二膦阴离子自由基已经使用元素硫和硒进行了容易的硫属元素化反应,分别提供了相应的噻二膦烷和硒二膦烷。
