Ferric chloride hexahydrate is a highly efficient catalyst for the regioselective arylation of α-amido sulfones. The products undergo further Friedel-Crafts alkylations with heteroaromatic or electron-rich arenes to afford unsymmetrical or bis-symmetrical triarylmethanes.
六水氯化铁是α-酰氨基砜区域选择性芳基化的高效催化剂。产物与杂芳烃或富电子芳烃进行进一步的 Friedel-Crafts 烷基化反应,得到不对称或双对称的三芳基甲烷。
