Unambiguously confirmed by low‐temperature in situ NMR experiments, X‐ray diffraction and vibrational spectroscopy, phosphonium‐carbenium superelectrophiles are shown to be generated in strong acidic conditions. Representing crucial intermediates, their exploitation allows for the synthesis of unprecedented fluorinated (cyclic) phosphine oxides.
低温原位NMR实验,X射线衍射和振动光谱法明确证实,phospho碳super超亲电子试剂在强酸性条件下产生。代表重要的中间体,它们的开发可以合成空前的
氟化(环状)氧化膦。
