  摘要：

  使用路易斯酸催化剂BiCl 3，设计了一种从1,4-萘醌合成2-氨基-1,4-萘醌和1,4-萘醌-2-硫化物的新方法。该方法底物适用范围广，产物提取容易。它成本低廉，需要温和且可持续的反应条件，并可提高产品收率。此外，本研究提出了第一种用胺和芳基肼/K 2 S 2 O 8进行单锅顺序胺芳基化的技术直接从 1,4-萘醌生产芳基化 2-氨基-1,4-萘醌。这种从经历自由基偶联反应的芳基肼产生芳基自由基的操作上直接的通过自由基捕获控制实验得到了很好的证明。

  A free radical reaction between 2-phenylthio-1,4-naphothoquinines and diethyl malonate initiated by manganese(III) acetate is described. This free radical reaction provides a new method for the synthesis of 6,11-dihydro-6,11-dioxo-12H-5-thianaphthacenes. This reaction was performed in various solvents, the best results were obtained in DMSO. With meta substituent on phenylthio ring, this reaction shows unusual high regioselectivity.
