For the first time, the direct synthesis of 1-methyl-phosphininium salts has been achieved by reacting aromatic λ,σ-phosphinines with the readily available dimethyl chloronium salt [(CH)Cl][Al(OTeF)]. The remarkably high electrophilicity of the alkylation reagent in combination with the weakly coordinating pentafluoro-orthotelluratoaluminate anion offers excellent conditions for this one-step approach. Our simple and quantitative access to 1-methyl-phosphininium salts will pave the way to explore the chemistry of such reactive species in more detail.
首次通过使芳族λ,σ-磷杂苯与容易获得的二甲基氯鎓盐[(CH)Cl][Al(OTeF)]反应实现了1-甲基-磷杂苯鎓盐的直接合成。烷基化试剂极高的亲电性与弱配位的五氟原碲酸铝阴离子相结合，为这种一步法提供了优异的条件。我们对1-甲基-磷杂苯鎓盐的简单且定量的制备方法将为更详细地探索此类活性物种的化学性质铺平道路。
