Transition-metal-free acid-promoted biaryl construction was achieved via intermolecular C–F/C–H cross-coupling. By treating 2-fluorobenzofurans with arenes and AlCl3, 2-arylbenzofurans including a bioactive natural product were obtained.
通过无过渡金属酸促进的分子间C-F/C-H交叉偶联实现了双芳基的构建。将2-氟苯并呋喃与芳烃和AlCl3处理后,得到了包括一种生物活性天然产物在内的2-芳基苯并呋喃。
