An effective synthesis of selenoxides by the oxidation of selenides with t-butyl hypochlorite in the presence of methanol and pyridine followed by hydrolysis is descrived. This oxidation method is particularly effective for the oxidation of selenides which possess electron-withdrawing groups. A synthesis of partially optically active selenoxide with bulky substituents can be achieved using a novel oxidation method.

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 ortho weak σ-electron-withdrawing group were used, triarylselenonium salts were obtained at room temperature, while ortho-(aryloxy)phenyl phenyl selanes could be produced from diaryl selenium oxides
已经实现了两组级联过程,这两个过程都是通过将苯插入到 Se═O 键中来引发的。区分这些过程的关键因素是基于二芳基硒氧化物的结构和反应条件。当使用含有邻位弱σ-吸电子基团的二芳基硒氧化物时,在室温下可得到三芳基硒盐,而在 100 °C 下可由二芳基硒氧化物制备邻-(芳氧基)苯基苯基硒烷。
