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 1,3- And 1,5-dimethylpyrazole-based syntheses. VI. Stilbene and 1,4-distyrylbenzene analogs containing 3-, 4-, and 5-pyrazolyl radicals, published in 1982-11-30, which mentions a compound: 84547-64-8, Name is 3-(Chloromethyl)-1-methyl-1H-pyrazole, Molecular C5H7ClN2, Product Details of 84547-64-8.
Condensation of 4-O2NC6H4CH2CO2H with pyrazolecarboxaldehydes, followed by reduction with SnCl2, gave I (R, R1 = H, H; Me, H; H, Me). Appropriate Wittig reactions gave II (R = 1-methyl-3-pyrazolyl, 4,5-dichloro-1-methyl-3-pyrazolyl, 1-methyl-5-pyrazolyl, 4-chloro-1-methyl-5-pyrazolyl), which showed intensive blue fluorescence in PhMe solution
This compound(3-(Chloromethyl)-1-methyl-1H-pyrazole)Product Details of 84547-64-8 was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
