39806-90-1<\/a>, A common heterocyclic compound, 39806-90-1, name is 4-Iodo-1-methyl-1H-pyrazole, molecular formula is C4H5IN2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

General procedure: First, Pd\/AlO(OH) NP catalyst (40.0 mg, 0.16 mmol %) and 1 mL of H2O\/MeOH (v\/v = 1\/1) were added to a Schlenk tube. Next, the halogenated compound (0.25 mmol) was added. Finally, NaBH4 (0.75 mmol) was added to the reaction mixture and the vessel was closed. The reaction then continued during vigorous stirring under ultrasonic conditions at room temperature and was monitored by GC. Most of the reactions were completed over a time period of 1.5 – 4 h. After completion of the reaction, the catalyst was removed via simple centrifugation at 6000 rpm and then washed three times with methanol and water and allowed to dry for further use. The solvent was evaporated under vacuum. The products were purified by flash column chromatography and the dehalogenated products were then determined by 1H NMR.<\/p>\n
