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, HPLC of Formula: 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.
《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》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(3-(Chloromethyl)-1-methyl-1H-pyrazole)HPLC of Formula: 84547-64-8.
