Adding a certain compound to certain chemical reactions, such as: 288-13-1, name is 1H-Pyrazole, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 288-13-1, Formula: C3H4N2<\/a><\/p>\n

To the three-necked flask, CuI (19 mg, 0.1 mmol, 10 mol%), 1,10-phenanthroline N,N’-dioxide (39 mg, 0.2 mmol, 20 mol%), Cs2CO3 (650 mg, 2.0 mmol). The reaction flask was evacuated under argon. To the p-nitroiodobenzene (249 mg, 1.0 mmol) was added pyrazole (102 mg, 1.5 mmol) and DMF (2 ml) under argon atmosphere. Reacted at room temperature for 18 hours until starting material is fully reacted (TLC detection reaction is complete). After completion of the reaction, a brown oil was obtained which was diluted with ethyl acetate. The inorganic salt was removed by filtration and the solvent was removed by rotary evaporation. The residue was eluted with petroleum ether \/ ethyl acetate Was purified by silica gel column chromatography to give 1-(4-nitrophenyl)pyrazole as a pale yellow oil. The yield was 82%.<\/p>\n

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1H-Pyrazole, other downstream synthetic routes, hurry up and to see.<\/p>\n","protected":false},"excerpt":{"rendered":"
