在无催化剂的条件下, 发展了一种合成3-硒代吲哚的有效方法. 使用硒代磺酸酯为硒化试剂, 通过S—Se键异裂生成阳离子中间体, 在温和条件下与吲哚发生亲电取代反应, 以28%~99%的产率合成了3-硒代吲哚产物.

关键词: 3-硒代吲哚, 硒化, 亲电取代, 无催化反应

An efficient method for synthesizing 3-selenoindoles without catalyst was developed. Selenosulfonates were employed as selenating reagents, generating cationic intermediates via S—Se bond heterolysis. Under mild conditions, it underwent electrophilic substitution reactions with indoles to synthesize 3-selenoindole products in 28%~99% yields.

Key words: 3-selenylindoles, selenation, electrophilic substitution, catalyst free
