A series of aromatic sulfonic acids is synthesized by subjecting arenes and NaHSO4·H2O to high-speed ball milling in the presence of P2O5. It is suggested the aromatic sulfonation occurs via in situ generated H2SO4 to give aromatic sulfonic acids. In some cases, formation of diaryl sulfones was observed.
在P 2 O 5存在下,芳烃和NaHSO 4 ·H 2 O经高速球磨合成一系列芳香族磺酸。建议芳族磺化通过原位生成的 H 2 SO 4 发生以产生芳族磺酸。在某些情况下,观察到二芳基砜的形成。
