The utilization of p-tolyl protecting groups and LiC₅F₄N and LiC₂F₅ as perfluoroarylation and alkylation reagents allows the formation of heteroleptic stannanes with three different substituents through stepwise deprotection with HX (X = Cl, Br) and substitution. The addition of water and acetonitrile to solid BrSn(C₅F₄N)₃ and BrSn(C₂F₅)(C₅F₄N)₂ emphasizes their Lewis acidic character.

含2,3,5,6-四氟吡啶基和五氟乙基取代基的路易斯酸性全氟有机锡卤化物的合成与性能

通过使用对甲苯基保护基和LiC ₅ F ₄ N和LiC ₂ F ₅作为全氟芳基化和烷基化试剂，可以通过用HX（X = Cl，Br）逐步脱保护并取代形成具有三个不同取代基的杂锡锡烷。向固体BrSn（C ₅ F ₄ N）₃和BrSn（C ₂ F ₅）（C ₅ F ₄ N）_2中加入水和乙腈强调了它们的路易斯酸性。
