The geminal frustrated Lewis pair (FLP) (F C ) SnCH P(tBu) (2) was prepared by reacting (F C ) SnCl with LiCH P(tBu) . It is neutral and contains an extremely electronegatively substituted, but relatively soft (hard-soft acid-base, HSAB) acidic tin function. Its FLP-type reactivity was proven by reaction with a variety of small molecules (CO , SO , CS , PhNCO, HCl, (Ph P)AuCl). However, it shows no reaction in H/D scrambling experiments with H /D mixtures and binds CO reversibly, as was observed by VT-NMR spectroscopy. Compound 2 and all its adducts were completely characterized by means of multinuclear NMR spectroscopy, elemental analysis, and X-ray diffraction experiments.
通过使(F C )SnCl与LiCH P(tBu)反应制备了偕二受阻路易斯酸碱对(FLP)(F C )SnCH P(tBu) (2)。它呈电中性，含有一个被极负电性取代但相对较软（软硬酸碱理论，HSAB）的酸性锡官能团。通过与多种小分子（CO 、SO 、CS 、PhNCO、HCl、(Ph P)AuCl）反应证明了其FLP型反应活性。然而，如变温核磁共振光谱所观察到的，它在与H /D混合物的H/D交换实验中不发生反应，并且能可逆地结合CO。化合物2及其所有加合物通过多核核磁共振光谱、元素分析和X射线衍射实验进行了全面表征。
