Abstract Triflic acid (TfOH) has been proven to be effective as a tolerant acidic mediator in electrophilic aromatic aroylation with CF3‐bearing aroyl chlorides. The TfOH‐mediated aroylation of fluorobenzene proceeds with high selectivity to give CF3‐bearing aryl fluorophenyl ketones in good yields, which are hardly obtained with the aid of AlCl3 or direct condensation reagents.
摘要 三氟甲磺酸 (TfOH) 已被证明在与含 CF3 的芳酰氯进行亲电芳族芳酰化反应中作为一种耐受酸性介质是有效的。TfOH 介导的氟苯芳酰化反应以高选择性进行,以良好的收率得到带有 CF3 的芳基氟苯基酮,这在 AlCl3 或直接缩合试剂的帮助下很难获得。
