The geminal frustrated Lewis pair (FLP) (F5C2)3SnCH2P(tBu)2 (2) was prepared by reacting (F5C2)3SnCl with LiCH2P(tBu)2. It is neutral and contains an extremely electronegatively substituted, but relatively soft (HSAB) acidic tin function. Its FLP‐type reactivity was proven by conversion with a variety of small molecules (CO2, SO2, CS2, PhNCO, HCl, and (Ph3P)AuCl), but it shows no reaction in H/D scrambling experiments and binds CO2 reversibly, as was observed by VT‐NMR spectroscopy. Compound 2 and all its adducts were completely characterised by means of multinuclear NMR spectroscopy, elemental analysis and X ray diffraction experiments.
