Abstract: The heterogeneous use of potassium permanganate, supported on copper (II) sulfate pentahydrate, provides a simple and effective means for oxidizing amines. Primary aliphatic amines, such as sec-butylamine, are oxidized to the corresponding carbonyl compounds in good to excellent yields. Primary aromatic amines, such as 4-chloroaniline, are converted quantitatively into the corresponding azo compounds. Carbon–carbon bond ...
