Gas-Chromatographic Study of Hydrazine Reaction with Metal 灏?Diketonates was written by Svistunova, I. V.;Shapkin, N. P.;Nikolaeva, O. V.. And the article was included in Russian Journal of General Chemistry (Translation of Zhurnal Obshchei Khimii) in 2002.Name: 4-Chloro-3,5-dimethyl-1H-pyrazole This article mentions the following:
When treated with hydrazine, metal 灏?diketonates undergo decomposition to form the corresponding pyrazoles, irresp. of the kinetic stability of the chelates. With substituted metal chelates, the main reaction products are pyrazoles bearing in position 4 the 绾?substituent of the complex. Other products are formed when the substituent has centers sensitive to nucleophilic substitution and/or elimination. The reaction can be used for structural assessment of the starting 灏?diketonate. In the experiment, the researchers used many compounds, for example, 4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8Name: 4-Chloro-3,5-dimethyl-1H-pyrazole).
4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8) belongs to pyrazole derivatives. Pyrazoles, a five-membered heterocycle containing two adjacent nitrogen atoms, are the core structures found in a number of molecules that possess a wide range of pharmaceutical and agricultural activities. The pyrazole ring is resistant to oxidation and reduction but the groups, such as alkyl and formyl attached to the ring, are oxidized to respective acids. Only electrolytic oxidation, ozonolysis, and a strong base cause ring opening.Name: 4-Chloro-3,5-dimethyl-1H-pyrazole
