A highly efficient transition-metal-free general method for the synthesis of polycyclic aromatic hydrocarbons like phenanthrenes and chrysenes (and tetraphene) from β-bromovinylarenes and arynes has been developed. The reactions proceed via an aryne Diels-Alder (ADA) reaction, followed by a facile aromatization. This is the first report on direct construction of chrysenes (and tetraphene) using the
已开发出一种高效的无过渡金属的通用方法,该方法可从β-溴乙烯基芳烃和芳烃中合成诸如菲和菲(及四苯)之类的多环芳烃。该反应通过芳烃Diels-Alder(ADA)反应进行,然后进行容易的芳构化。这是有关使用ADA方法直接构建车菊(和四苯酚)的第一份报告。与仅限于9/10取代衍生物的文献方法不同,该方法可使用多种官能化的菲。
