Dibenzofuran and its derivatives are ubiquitous and important medicinal and natural products. Many contain electron-donating substituents. Herein, we report a Pd-catalysed C−H functionalisation protocol that works with electron-rich arenes. We use tetrabutylammonium acetate (NBu4OAc), which we suspect can act as base and ligand, rendering this protocol a simple and efficient route to dibenzofurans
二苯并呋喃及其衍生物是普遍存在且重要的药用和天然产物。许多含有供电子取代基。在此,我们报告了一种适用于富电子芳烃的 Pd 催化的 C−H 功能化方案。我们使用乙酸四丁基铵 (NBu 4 OAc),我们怀疑它可以充当碱和配体,使该方案成为二苯并呋喃的简单而有效的途径。
