magnetically separable Lewis acid catalyst and successfully used for the one-pot synthesis of α -aminonitriles. A broad range of substrates including the aromatic and heteroaromatic aldehydes, cyclic ketones (cyclopentanone, cyclohexanone and cycloheptanone), aryl–alkyl ketones, diaryl ketones and tetralones, isatin derivatives and acenaphthenequinone were condensed with amines (aliphatic and aromatic) and trimethylsilyl
制备了Fe 3 O 4磁性纳米颗粒负载的BF 3作为新型的可磁分离的路易斯酸催化剂,并成功用于一锅法合成 α- 氨基腈。广泛的底物包括芳族和杂芳族醛,环酮(环戊酮,环己酮和环庚酮),芳基-烷基酮,二芳基酮和四氢萘酮,靛红衍生物和苯醌与胺(脂族和芳族)和三甲基甲硅烷基氰化物缩合。所有反应均在短时间内完成,并以良好至极好的收率获得了产物。该催化剂可以循环使用几次,而不会降低效率。最后, α 含腺嘌呤的-氨基腈已成功合成。
