are formed depending on the nature of the aryl group and the substituents in the anthracene. The first one is the product of [4+3] cycloaddition of cyclopropane to a diene moiety of anthracene. The second one also has a seven-membered ring and is formed by the Lewis acid catalyzed electrophilic attack of cyclopropane onto the C9 atom of anthracene followed by intramolecular attack of the formed arenonium
首次研究了2-芳基-1,1-环丙烷二酯与蒽衍生物的反应。根据芳基的性质和蒽中的取代基,形成三种反应产物。第一个是环丙烷与蒽的二烯部分发生[4+3]环加成的产物。第二个也具有七元环,由路易斯酸催化的环丙烷亲电攻击蒽的 C9 原子,然后形成的芳烃离子对起始环丙烷的芳基进行分子内攻击而形成。最后,形成常见的 Friedel-Crafts 乘积。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
