Density functional theory calculations reveal that activation of the Kobayashi aryne precursor consists of pseudo-S_N2-type attack of the fluoride ion at the silicon atom, aryl–Si bond cleavage, and irreversible triflate (^–OTf) dissociation. The rate-determining step is determined to be addition of the fluoride ion to the trimethylsilyl group.

氟化物诱导的小林前体活化的机理：通过五配位硅酸酯络合物的伪SN2途径。

密度泛函理论计算显示小林芳炔前体的活化由伪S的_Ñ在硅原子上的氟离子的2型攻击，芳基-Si键的裂解，和不可逆的三氟甲磺酸酯（^- OTF）解离。确定速率的步骤是将氟离子加成到三甲基甲硅烷基上。
