A variety of substituted diarylsulfones could be synthesized by simple arenes and 3CdSO₄·xH₂O in the presence of P₂O₅ under high-speed ball milling. It was suggest the aromatic sulfonation was performed by arene and in situ generated H₂SO₄, following-up by electrophilic substitution with another arene to give diarylsulfone.

借助机械化学方法从芳烃和3CdSO ₄ ·xH ₂ O轻松合成二芳基砜

在高速球磨条件下，在P ₂ O ₅存在下，通过简单的芳烃和3CdSO ₄ ·xH ₂ O可以合成多种取代的二芳基砜。这表明芳族磺化反应是由芳烃进行的，并原位生成H ₂ SO ₄，随后通过亲电取代另一种芳烃得到二芳基砜。
