Selenabenzenes 12a–c with two electron-withdrawing groups (EWGs) at the 2- and 6-positions were synthesized from dihalides 1a, 1b and 1c′via seven steps and isolated as stable compounds at room temperature. According to X-ray structural analysis of the dibenzoyl derivative 12c, the six-membered ring containing a selenium atom is almost planar and the structure of the selenium atom is tetrahedral with
由二卤化物1a,1b和1c'经过7个步骤合成了在2和6位带有两个吸电子基团(SWG)的硒苯12a–c。根据二苯甲酰基衍生物12c的X射线结构分析,含有硒原子的六元环几乎是平面的,并且硒原子的结构是具有四个sp 3杂化轨道的四面体。
