Our results show that the effect of microwave irradiation on the reactions studied was a shortening of the reaction times and a smooth increase in the yields. The subsequent reactions of the product with some nucleophiles are discussed. The structure of the products was proven by elemental analysis, IR and NMR spectra. <a href="/1420-3049/5/2/167">Full article</a> </div> </div> <a href="#" class="abstract-figures-show" data-counterslink = "https://www.mdpi.com/1420-3049/5/2/167/show" ><span >►</span><span style=" display: none;">▼</span> Show Figures </a><div class="abstract-image-preview "><div class="arrow left-arrow" id="prev3017"><i class="fa fa-caret-left"></i></div><div class="arrow right-arrow" id="next3017"><i class="fa fa-caret-right"></i></div><div class="absgraph cycle-slideshow manual" data-cycle-fx="scrollHorz" data-cycle-timeout="0" data-cycle-next="#next3017" data-cycle-prev="#prev3017" data-cycle-progressive="#images3017" data-cycle-slides=">div" data-cycle-log="false"><div class='openpopupgallery cycle-slide' data-imgindex='0' data-target='article-3017-popup'><span class="helper"></span><img src="data:image/gif;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs=" data-src="https://pub.mdpi-res.com/molecules/molecules-05-00167/article_deploy/html/images/molecules-05-00167-sch001-550.jpg?1668240755" alt="" style="border: 0;"><p>Scheme 1</p></div><script id="images3017" type="text/cycle" data-cycle-split="---"><div class='openpopupgallery' data-imgindex='1' data-target='article-3017-popup'><span class="helper"></span><img src='https://pub.mdpi-res.com/molecules/molecules-05-00167/article_deploy/html/images/molecules-05-00167-sch002-550.jpg?1668240750'><p>Scheme 2</p></div></script></div></div><div id="article-3017-popup" class="popupgallery" style="display: inline; line-height: 200%"><a href="https://pub.mdpi-res.com/molecules/molecules-05-00167/article_deploy/html/images/molecules-05-00167-sch001-550.jpg?1668240755" title=" <strong>Scheme 1</strong><br/> <p></p> <strong style='display: block; margin-top: 10px; font-size: 18px;'><a style='color: #fff' href='/1420-3049/5/2/167'>Full article</a></strong> "></a><a href="https://pub.mdpi-res.com/molecules/molecules-05-00167/article_deploy/html/images/molecules-05-00167-sch002-550.jpg?1668240750" title=" <strong>Scheme 2</strong><br/> <p></p> <strong style='display: block; margin-top: 10px; font-size: 18px;'><a style='color: #fff' href='/1420-3049/5/2/167'>Full article</a></strong> "></a></div> </div> </div> <div class="generic-item article-item"> <input class="article-list-checkbox export-element" type="checkbox" name="articles_ids[]" value="3016" data-select-all-name="article-listing"> <div class="article-content"> <div class="label right label__btn"> <span style="font-size: 12px; color: #1a1a1a;"> 34 KiB   </span> <a href="/1420-3049/5/2/162/pdf?version=1403112316" class="UD_Listings_ArticlePDF" title="Article PDF" data-name="Diels-Alder Cycloaddition of Cyclopentadiene to a Bis-naphthoquinone" data-journal="molecules"> <i class="material-icons custom-download"></i> </a> </div> <div class="article-icons"><span class="label openaccess" data-dropdown="drop-article-label-openaccess" aria-expanded="false">Open Access</span><span class="label articletype">Article</span></div> <a class="title-link" href="/1420-3049/5/2/162">Diels-Alder Cycloaddition of Cyclopentadiene to a Bis-naphthoquinone</a> <div class="authors"> by <span class="inlineblock "><strong>Margaret A.
