Although ultimately not isolable for X‐ray structural characterization, the free perfluorinated trityl cation was shown to be observable in neat triflic acid, which represents milder conditions than previous reports of this cation in “magic acid” or oleum. A triflate‐bound species could be generated in organic solvents using stoichiometric amounts of triflic acid and was shown to be synthetically viable
尽管对于X射线结构表征最终是不可分离的,但在纯三氟甲磺酸中可观察到游离的全氟三苯甲基阳离子,这比以前在“魔术酸”或发烟硫酸中对该阳离子的报道要温和。用化学计量的三氟甲磺酸可在有机溶剂中生成与三氟甲磺酸盐结合的物质,并显示出从Et 3 SiH提取氢化物的合成可行性。结果表明,C 6 F 5环上的对位是阳离子分解的主要攻击点。
