α-Oxoketenes and cyclohexadiene α-oxoketenes are reactive intermediates, particularly the latter due to their high re-aromatization potential. In this communication, we report photolytic studies on the generation of such species from 4-OMe and 4-OMOM protected resorcylate dioxinones and their trapping to give resorcylate esters and amides as well as the formation of adducts with enol-ethers as trapping
α-Oxoketenes和环己二烯α - oxoketenes是反应性的中间体,尤其是后者,由于它们的高再芳构化的潜力。在这篇通讯中,我们报告了从 4-OMe 和 4-OMOM 保护的间苯二酸二恶英产生此类物质的光解研究,以及它们的捕获以产生间苯二酸酯和酰胺,以及与烯醇-醚作为捕获试剂的加合物的形成。
