Bis(trimethylsilyl)selenide (HMDSS) acts as an efficient reagent in the TBAF catalyzed reaction with different substituted epoxides, episulfides, and aziridines, leading to β -functionalized diselenides in a highly regio- and stereoselective way. When using α -bromo alkyl ethers as trapping agent, 1,3-oxaselenolanes and 1,3-thiaselenolanes can be isolated, while 1,3-selenazolidines could be obtained
双(三甲基甲硅烷基)硒化物 (HMDSS) 在与不同取代环氧化物、环硫化物和氮丙啶的 TBAF 催化反应中充当有效试剂,以高度区域和立体选择性的方式产生 β-官能化的二硒化物。使用α-溴代烷基醚作为捕集剂时,可以分离出1,3-氧杂硒代烯醇烷和1,3-硫硒代烯醇烷类,而将β-氨基二硒化物还原,然后用不同的醛原位处理可以得到1,3-硒代硒代烷烃.
