The chemical reduction of alkyl, aryl, and benzyl selenocyanates, as masked selenols, using Rongalite is investigated. As a result, the corresponding diselenides were obtained selectively in very good to excellent yields. Additionally, a simple methodology is described using the in-situ generated benzyl selenolate anion to promote nucleophilic substitution, epoxide ring opening, and Michael addition
研究了使用雕白粉对烷基、芳基和苄基硒氰酸酯(作为掩蔽硒醇)进行化学还原。结果,以非常好到优异的产率选择性地获得了相应的二硒化物。此外,还描述了一种简单的方法,使用原位生成的硒酸苄酯阴离子来促进亲核取代、环氧化物开环和迈克尔加成反应。
