二芳基卡宾离子的“阳离子池”是由二芳基甲烷的氧化C-H键通过阳极氧化解离而产生的。由此产生的“二芳基碳正离子池”与各种亲核试剂反应，如烯丙基硅烷、烯酮硅基缩醛和芳香族化合物。实现了“二芳基碳正离子池”的还原同偶联。这样得到的二聚体也是通过氧化C-C键解离而形成的“二芳基碳正离子池”的前体。[反应：见正文]
"Cation pools" of diarylcarbenium ions have been generated by the oxidative C-H bond dissociation of diarylmethanes using anodic oxidation. "Diarylcarbenium ion pools" thus generated react with various nucleophiles, such as allylsilanes, ketene silyl acetals, and aromatic compounds. The reductive homocoupling of the "diarylcarbenium ion pool" has been achieved. The dimer thus obtained also serves as a precursor of the "diarylcarbenium ion pool" via oxidative C-C bond dissociation. [reaction: see text]
