dialkyl diselenides and selenides is described through reaction of bis(trimethylsilyl)selenide with epoxides, thiiranes, and aziridines catalyzed by tetrabutylammonium fluoride. Selective formation of a wide variety of β-hydroxy, β-mercapto, and β-amino diselenides and selenides is achieved by controlling the reaction conditions in the regioselective attack of the silyl selenide onto the ring-strained
通过双(三甲基甲硅烷基)硒化物与环氧化物、硫杂环丙烷和氮丙啶在四丁基氟化铵催化下的反应,描述了一种合成 β-取代的二烷基二硒化物和硒化物的新方法。选择性形成多种 β-羟基、β-巯基和 β-氨基二硒化物和硒化物是通过控制硒化甲硅烷对环应变杂环的区域选择性攻击的反应条件来实现的。所有反应都以高度区域选择性和对映体保守的方式发生,以良好到高产率提供标题化合物。测量硒 77 NMR 化学位移以验证 β 取代的二硒化物和硒化物的选择性形成。
