摘　　要：苯骈三氮唑和胺(伯、仲胺:芳胺、杂环胺或杂环芳胺)、苯甲醛发生Mannich反应,生成N-取代-1-苯骈三氮唑基苄胺(2a—21),2a—21与硒氢化钠反应生成二苄基二硒醚,反应条件温和,产率高,胺和苯骈三氮唑均可回收再利用。N-substituted-1-benzotriazolylbenzylamines (2) were obtained from the Mannich reaction of benzotriazole with benzaldehyde and amines: primary and secondary amines. Sodium hydrogen selenide reacted with 2 in mild conditions to give dibenzyl-diselenide with high yield. Benzotriazole and amines were removed and recovered.
