New organometallic superacids of sulfonic acid derivatives were designed on the basis of acidity enhancement by internal bonding with an electron-pair acceptor group -BX₂ (X = H, F, Cl, Br). The acidity enhancement in the gas phase was assessed using the B3LYP/6-311++G(d,p) method. Two classes of superacids were devised. The first series was based on a cyclopentadiene ring carrying a -SO₂(CH₂)₃BX₂ or -SO(OH)(CH₂)₃BX₂ group, and the second series was designed by substituting the three C-H of CH₃SO₃H by three –(CR₂)₃BX₂ groups (R = H, F). An organometallic hyperacid of relatively small size with Δ_acidG of 229.5 kcal mol^-1 was obtained.

在通过与电子对受体基团-BX ₂（X = H，F，Cl，Br）进行内部键合提高酸度的基础上，设计了磺酸衍生物的新型有机金属超酸。使用B3LYP / 6-311 ++ G（d，p）方法评估气相中的酸度增强。设计了两类超酸。第一个系列基于带有-SO ₂（CH ₂）₃ BX ₂或-SO（OH）（CH ₂）₃ BX ₂基团的环戊二烯环，第二个系列是通过取代CH ₃的三个CH设计的SO ₃ H乘以3 –（CR ₂）₃ BX₂组（R = H，F）。获得具有229.5kcal mol ^-1的Δ_酸G的相对较小尺寸的有机金属高_酸。
