of the product was confirmed by the X‐ray analysis. Novel trifluoromethylated corannulenes, including the versatile 4,9‐dibromo‐1,2‐bis(trifluoromethyl)corannulene, were obtained by various established ring‐closing reactions. Besides the use of hexafluorobutyne for the construction of fluoranthenes by Diels–Alder reaction as precursor molecules to form 1,2‐disubstituted corannulenes, bis(pentafluorophenyl)acetylene
报道了带有吸电子基团(F,CF 3,C 6 F 5)的Corannulenes的合成和性质。邻苯二酚的直接氟化(C 20 H 10)用二氟化氙进行,X射线分析证实了产物的晶体结构。通过各种已建立的闭环反应,获得了新颖的三氟甲基化氢化萘,包括通用的4,9-二溴-1,2-双(三氟甲基)氢化萘。除了使用六氟丁炔通过狄尔斯-阿尔德反应(Diels-Alder reaction)构建前叉分子以形成1,2-二取代的Corannulenes来构建荧蒽外,还使用双(五氟苯基)乙炔作为亲二烯体。通过单晶X射线分析确定了三氟甲基化氢化萘的分子结构和晶体堆积,并将其与已知的溴化和三氟甲基化氢化萘酯进行了比较。
