[structure: see text]. A stable selenenic acid was synthesized by direct oxidation of a selenol bearing a novel bowl-type substituent with H2O2, and its structure was established by X-ray crystallographic analysis. Selenenyl sulfides obtained by the reaction of the selenenic acid with 1,4-dithiols were reduced to the corresponding selenol by treatment with a tertiary amine, thus achieving the experimental
[结构:见文字]。通过用H 2 O 2直接氧化带有新型碗型取代基的硒醇来合成稳定的硒酸,并通过X射线晶体学分析确定其结构。通过用叔胺处理,将硒酸与1,4-二硫醇反应获得的硒烯基硫化物还原为相应的硒醇,从而实现了谷胱甘肽过氧化物酶催化循环中三个过程的实验证明。
