摘要: The geminal frustrated Lewis pair (FLP) (F5 C2 )3 SnCH2 P(tBu)2 (2) was prepared by reacting SnCl with LiCH2 . It is neutral and contains an extremely electronegatively substituted, but relatively soft (hard-soft acid-base, HSAB) acidic tin function. Its FLP-type reactivity proven reaction a variety of small molecules (CO2 , SO2 CS2 PhNCO, HCl, (Ph3 P)AuCl). However, it shows no in H/D scrambling experiments H2 /D2 mixtures binds CO2 reversibly, as observed VT-NMR spectroscopy. Compound 2 all its adducts were completely characterized means multinuclear NMR spectroscopy, elemental analysis, X-ray diffraction experiments.
