近年来符合休克尔规则的,经典的6π芳香环以外的大环或多环芳香族化合物的合成及其应用的开发曰益受到人们的重视。本文简要介绍含有三氟甲基及三氟乙酰基的苯并10π-芳杂环化合物的合成及其结构的确定。此类化合物目前文献中尚未见报导。 邻位芳香族二胺作为亲核试剂与反式三氟乙酰基乙氧基乙烯反应,得到乙氧基
In recent years, in line with the Hicker rules, the classic 6π aromatic ring outside the ring or polycyclic aromatic compound synthesis and application development said by the people’s attention. This article briefly introduced the synthesis of trifluoromethyl and trifluoroacetyl benzo 10π-aromatic heterocycles and the determination of their structures. No such reports have been reported in the current literature. The ortho-aromatic diamine is reacted with trans-trifluoroacetylethoxyethylene as a nucleophile to give the ethoxy
