We describe the synthesis of [-PhP(O)(CH)SbPh] ([2]), an intramolecularly base-stabilized stibonium Lewis acid which was obtained by reaction of [-PhP(CH)SbPh] with NOBF. This cation reacts with fluoride anions to afford the corresponding fluorostiborane -PhP(O)(CH)SbFPh, the structure of which indicates a strengthening of the PO → Sb interaction. When deployed in fluoride-containing POPC unilamellar vesicles, [2] behaves as a potent fluoride anion transporter whose activity greatly exceeds that of [PhSb].
我们描述了[-PhP(O)(CH)SbPh]（[2]）的合成，它是一种分子内碱稳定的锑鎓路易斯酸，通过[-PhP(CH)SbPh]与NOBF反应得到。该阳离子与氟阴离子反应生成相应的氟代硼烷-PhP(O)(CH)SbFPh，其结构表明PO→Sb相互作用增强。当[2]应用于含氟的POPC单层囊泡时，它表现为一种有效的氟阴离子转运体，其活性大大超过[PhSb]。
