Two sets of cascade processes have been realized, both of which were initiated with a benzyne insertion into the Se═O bond. The key factors to differentiate these processes are based on the structures of diaryl selenium oxides and reaction conditions. When diaryl selenium oxides containing an weak σ-electron-withdrawing group were used, triarylselenonium salts were obtained at room temperature, while -(aryloxy)phenyl phenyl selanes could be produced from diaryl selenium oxides at 100 °C.
已经实现了两组级联过程，它们都是由苯炔插入 Se═O 键引发的。区分这些过程的关键因素取决于二芳基硒氧化物的结构和反应条件。当使用含有较弱 σ-吸电子基团的二芳基硒氧化物时，在室温下可以得到三芳基硒翁盐，而在 100°C 下可以从二芳基硒氧化物得到 -(芳氧基)苯基苯基硒烷。
