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

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

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