Operationally simple and generally applicable arene nitration with cheap and easily accessible chemicals has been a long-sought transformation in the synthetic organic community. In this work, we realized this goal with nontoxic and inexpensive Fe(NO3)3·9H2O as the nitro source and easily recyclable solvent hexafluoroisopropanol as the promotor via a network of hydrogen-bonding interactions. As a result
使用廉价且易于获得的化学品进行操作简单且普遍适用的芳烃硝化一直是合成有机界长期以来寻求的转变。在这项工作中,我们以无毒且廉价的Fe(NO 3 ) 3 ·9H 2 O作为硝基源,并通过氢键相互作用网络以易于回收的溶剂六氟异丙醇作为促进剂实现了这一目标。由于该方案相对温和且可靠性高,实现了各种高功能化天然产物和市售药物的后期硝化。
