Oxidation of styrylpyridinium dyes by permanganate ion was written by Dash, Sukalyan;Mishra, Bijay K.. And the article was included in Bulletin of the Chemical Society of Japan in 1994.Synthetic Route of C10H16BrN This article mentions the following:
The oxidation of N-alkyl substituted styrylpyridinium bromides in both KMnO4 and cetyltrimethylammonium permanganate (CTAP) results in the formation of both of the corresponding substituted benzaldehydes. The oxidation in aqueous medium is catalyzed by acid whereas in CHCl3 the reaction proceeds under neutral conditions. However, the reaction proceeds through the same mechanism in both the media. The faster rate of oxidation in aqueous medium by KMnO4 than that in CHCl3 medium by CTAP is rationalized through a hydrophobic effect. The overall rate equation can be represented as rate = k[Substrate]1.5[Oxidant]-0.75 in aqueous medium and rate = k[Substrate]0.5[Oxidant]-1 in CHCl3. From the substituent effect a transition state with low electron d. at the olefinic carbon is proposed. In the experiment, the researchers used many compounds, for example, 1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6Synthetic Route of C10H16BrN).
1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Synthetic Route of C10H16BrN
