Abstract The selective reduction of aryl nitro compounds in the presence of sensitive functionalities, including halide, carbonyl, nitrile, and ester substituents, under ultrasonic irradiation at 35 kHz is reported in yields of 39–98%. Iron powder proved superior to stannous chloride with high tolerance of sensitive functional groups and high yields of the desired aryl amines in relatively short reaction
摘要 据报道,在 35 kHz 超声波照射下,在敏感官能团(包括卤化物、羰基、腈和酯取代基)存在的情况下,芳基硝基化合物的选择性还原率为 39-98%。铁粉证明优于氯化亚锡,具有对敏感官能团的高耐受性和在相对较短的反应时间内所需芳胺的高产率。简单的实验程序和纯化也使芳基硝基化合物的铁还原优于其他还原方法。
