On December 15, 2010, Chandrappa, S.; Vinaya, K.; Ramakrishnappa, T.; Rangappa, K. S. published an article.Safety of 3-Chloro-4-nitrobenzonitrile The title of the article was An efficient method for aryl nitro reduction and cleavage of azo compounds using iron powder/calcium chloride. And the article contained the following:
A novel, efficient Fe/CaCl2 system was revealed for the reduction of nitro-arenes and reductive cleavage of azo compounds by catalytic transfer hydrogenation. The selective reduction of nitro compounds in the presence of sensitive functional groups including halides, carbonyl, hydroxyl, aldehyde, Me, methoxy, acetyl, nitrile, and ester substituents with an excellent yields is reported. The simple exptl. procedure and easy purification make the protocol advantageous. The experimental process involved the reaction of 3-Chloro-4-nitrobenzonitrile(cas: 34662-29-8).Safety of 3-Chloro-4-nitrobenzonitrile
The Article related to nitro aryl reduction iron calcium chloride catalytic transfer hydrogenation, azo aromatic cleavage iron calcium chloride catalytic transfer hydrogenation, aryl amine preparation and other aspects.Safety of 3-Chloro-4-nitrobenzonitrile
