A study of some parameters which influence the oxidation of 2- and 4-methylquinolines with selenium dioxide (or selenious acid) in dioxane has allowed to correct some erroneous opinions of this method and to elaborate a general, simple, fast, and cheap procedure of oxidation of methylquinolines having a methyl group in the position 2 or 4.

Review

4-methylquinoline oxidation really works

Review:

This article/communication described the preapration of 2 and 4-quinolinecarboxaldehyde using 2 and 4-methylquinoline in the presence of selenous acid in refluxing dioxane. While the procedure explicitly stated the use of selenous acid, selenium dioxide can also be...
