Sources of common compounds: 34091-51-5

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, 5-Iodo-1-methyl-1H-pyrazole, other downstream synthetic routes, hurry up and to see.

Adding a certain compound to certain chemical reactions, such as: 34091-51-5, name is 5-Iodo-1-methyl-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 34091-51-5, Computed Properties of C4H5IN2

lsopropylmagnesium chloride (0.55 ml, 1.10 mmol) was added to a solution of 5- iodo-1 -methyl-1 H-pyrazole (208 mg, 1.00 mmol)[ prepared according to Effenberger, F.; Krebs, A. J. Org. Chem. 1984, 49, 4687] in tetrahydrofuran (5 ml) at -78 0C. The reaction mixture was stirred at this temperature for 30 min. A solution of bis(1 ,1-dimethylethyl) (E)- 1 ,2-diazenedicarboxylate (253 mg, 1.100 mmol) in 5 mL of THF was added at -78 0C. The reaction mixture was warmed to RT and saturated NH4CI solution was added to quench the reaction. The organic layer was separated and the aqueous layer was extracted with ether. The combined organic layers were washed with brine, dried (Na2CO3) and concentrated to give the crude product, which was purified on a silica gel column to give 180 mg (57.6%) of product. LCMS MS (M+H+): 313.2.

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, 5-Iodo-1-methyl-1H-pyrazole, other downstream synthetic routes, hurry up and to see.
