Ag&lt;span style=&quot;vertical-align: -0.4em; font-size: 0.8em; line-height: 0.8em;&quot;&gt;2&lt;/span&gt;O catalyzed the in situ oxidation of hydroquinone and 3-indolylhydroquinone intermediates, whereas ferrite solid acid, Fe&lt;span style=&quot;vertical-align: -0.4em; font-size: 0.8em; line-height: 0.8em;&quot;&gt;3&lt;/span&gt;O&lt;span style=&quot;vertical-align: -0.4em; font-size: 0.8em; line-height: 0.8em;&quot;&gt;4&lt;/span&gt;/PVP–PWA, with a 1:4:1 ratio of Fe&lt;span style=&quot;vertical-align: -0.4em; font-size: 0.8em; line-height: 0.8em;&quot;&gt;3&lt;/span&gt;O&lt;span style=&quot;vertical-align: -0.4em; font-size: 0.8em; line-height: 0.8em;&quot;&gt;4&lt;/span&gt;, PVP, and PWA, catalyzed the activation of quinones. The efficiency of this catalytic domino approach was established by a broad scope of substrates involving a variety of hydroquinones and quinones to give high yields (81–97%) of 3-indolylquinones.
