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. 17635-44-8, name is 3,4,5-Tribromopyrazole belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. Product Details of 17635-44-8
General procedure: 3,4,5-Tribromopyrazole (9a; 762 mg, 2.5 mmol) or 3,5-dibromo-4-nitropyrazole(9b; 677 mg, 2.5 mmol), o-quinone methide precursor 2(2.5 mmol) and K2CO3 (only for 9a, 1.035 g, 7.5 mmol) were refluxedfor 4 h in DMF (10 mL). Product was isolated analogously to compound4a.
The synthetic route of 17635-44-8 has been constantly updated, and we look forward to future research findings.
