Zincke reaction - Wikipedia
The Zincke reaction is an organic reaction, named after Theodor Zincke, in which a pyridine is transformed into a pyridinium salt by reaction with 2,4-dinitro-chlorobenzene and a primary amine [1][2][3][4] The Zincke reaction should not be confused with the Zincke-Suhl reaction or the Zincke nitration
Zincke aldehyde - Wikipedia
Zincke aldehydes, or 5-aminopenta-2,4-dienals, are the product of the reaction of a pyridinium salt with two equivalents of any secondary amine, followed by basic hydrolysis
Zincke反应 - 维基百科，自由的百科全书
以仲胺替代伯胺时，最终产生开链的产物——5-氨基-2,4-戊二烯醛类，称为 Zincke 醛。 [10] 2006年和2007年，日本 [11] 和美国 [12] 的两个研究小组都声称，他们通过 N -芳基吡啶盐氯化物和取代苯胺（或脂肪胺）反应，合成如下一12元环的二氮杂轮烯分子（1），从而“重新发现”Zincke 这一类反应。不久后德国化学家 Christl [13] 在 Angewandte Chemie 上发文，指出上述反应与有100余年历史的 Zincke 反应实属异曲同工，而且，这两个团队提出的产物结构是错误的——产物中并不含12元环，其结构只是简单六元的吡啶鎓盐（2）而已。
Reactivity and Synthesis Inspired by the Zincke Ring-Opening of . . .
The century-old Zincke process for ring-opening of pyridinium salts produces 5-amino-2,4-pentadienals, a type of donor–acceptor dienes known as Zincke aldehydes Inspired by this reasonably general

The Zincke reaction is an overall amine exchange process that converts N -(2,4- dinitrophenyl)pyridinium salts, known as Zincke salts, to N -aryl or N -alkyl pyri- diniums upon treatment with the appropriate aniline or alkyl amine
Unraveling the Mechanism of Cascade Reactions of Zincke Aldehydes
The thermal pericyclic cascade rearrangement of Zincke aldehydes (5- (dialkylamino)-2,4-pentadienals) to afford Z -α,β,γ,δ-unsaturated amides discovered by the Vanderwal group has been studied in depth using quantum mechanical methods
Zincke Reaction - SynArchive
The Zincke reaction is the reaction between 1-(2,4-dinitrophenyl)pyridinium salts and amines Primary amines yield pyridinium salts while secondary amines yield 5-(dialkylamino)penta-2,4-dienals (Zincke aldehydes)
