Abstract Nitration of N-acetyl anilides using a simple combination of AgNO3 and K2S2O8 as a stable nitro source and an oxidant, respectively, was explored. The reaction was practical to operate and proceeded under considerably mild reaction conditions (reflux in acetonitrile) within acceptable reaction time (6 h). The para-substituted N-acetyl anilides gave only ortho-nitrated products in moderate
摘要 探索了使用AgNO 3和K 2 S 2 O 8的简单组合分别作为稳定的硝基源和氧化剂对N-乙酰苯胺的硝化。该反应在可接受的反应时间(6小时)内可在相当温和的反应条件(在乙腈中回流)下实际操作和进行。对位取代的N-乙酰苯胺仅产生邻位硝化产物,产率适中(产率 30-63%)。邻位、间位或未取代的N-乙酰苯胺产生硝化产物的混合物(30-72%的总产率),优先在对位而不是邻位(邻位:对位;1.0:1.1-1.0:2.8)。
