In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called 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, published in 2002-10-31, which mentions a compound: 84547-64-8, Name is 3-(Chloromethyl)-1-methyl-1H-pyrazole, Molecular C5H7ClN2, Name: 3-(Chloromethyl)-1-methyl-1H-pyrazole.
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.
Compound(84547-64-8)Name: 3-(Chloromethyl)-1-methyl-1H-pyrazole received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(3-(Chloromethyl)-1-methyl-1H-pyrazole), if you are interested, you can check out my other related articles.
