In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 34091-51-5, name is 5-Iodo-1-methyl-1H-pyrazole belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. Product Details of 34091-51-5
A solution of 5-iodo-l -methyl-lH-pyrazole (1.90 g,9.14 mmol),2-(4,4-difluorocyclohex-l-en-l-yl)-4,4,5,5-tet-ramethyl-l,3,2-dioxaborolane(1.00 g, 4.10 mmol), tetrakis (triphenylphosphine)palladium(O) (240 mg, 0.208mmol), and cesium carbonate (2.70 g, 8.29 mmol) in 1,4-dioxane (10 mL) andwater (5.0 mL) was stirred at 90 C. for 4 hours. After allowing to cool, thereaction solution was subjected to extraction with ethyl acetate (50 mL), andthe organic layer was dried over anhydrous sodium sulfate. The organic layer was concentrated under reduced pressure, and the residue was purified with column chromatography (hexane/ethyl acetate=9:l) to yield the title compound(767 mg, 94%) as a colorless oil.
The synthetic route of 34091-51-5 has been constantly updated, and we look forward to future research findings.
