The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 3-(Chloromethyl)-1-methyl-1H-pyrazole( cas:84547-64-8 ) is researched.HPLC of Formula: 84547-64-8.Levkovskaya, G. G.; Bozhenkov, G. V.; Larina, L. I.; Mirskova, A. N. published the article 《New synthesis and properties of 3-alkyl-, 3-chloroalkyl-, 3-perfluoroalkyl-, and 3-aryl-1-methyl-5-halopyrazoles from chloro(bromo)vinyl ketones and N,N-dimethylhydrazine》 about this compound( cas:84547-64-8 ) in Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii). Keywords: regioselective heterocyclization halovinyl ketone dimethylhydrazine; halopyrazole preparation; pyrazole halo preparation. Let’s learn more about this compound (cas:84547-64-8).
A new regioselective heterocyclization was revealed in the reaction of 2-chloro- and 2,2-dichloro(bromo)vinyl ketones with N,N-dimethylhydrazine to afford 3-substituted 1-methyl-5-halopyrazoles. The reaction is accompanied by elimination of Me halide and formation of up to 90% of N,N,N-trimethylhydrazinium halide as the second product.
I hope my short article helps more people learn about this compound(3-(Chloromethyl)-1-methyl-1H-pyrazole)HPLC of Formula: 84547-64-8. Apart from the compound(84547-64-8), you can read my other articles to know other related compounds.
