Ernst Carl Theodor Zincke war ein deutscher Chemiker, der von 1875 bis 1913 als Professor an der Universität Marburg wirkte. Nach ihm sind die Zincke-Reaktion, die Zincke-Suhl-Reaktion sowie die Zincke-Nitrierung benannt.
Ernst Carl Theodor Zincke (19 May 1843 – 17 March 1928) was a German chemist and the academic adviser of Otto Hahn. Life. Theodor Zincke was born in Uelzen on 19 May 1843. He became a pharmacist and graduated in Göttingen with his Staatsexamen. He began studying chemistry with Friedrich Wöhler and received his Ph.D in 1869.
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] The Zincke reaction should not be confused with the Zincke-Suhl reaction or the Zincke nitration.
The Zincke–Suhl reaction is a special case of a Friedel-Crafts alkylation and was first described by Theodor Zincke and Suhl in 1906.
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.
