Adding a certain compound to certain chemical reactions, such as: 50877-42-4, name is 1-Benzyl-4-iodo-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 50877-42-4, Safety of 1-Benzyl-4-iodo-1H-pyrazole
General procedure: To a solution of 4-iodo-1-methyl-1H-pyrazole (3.0 g, 14.4 mmol, 1.0 eq.), 4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene (xantphos) (835 mg, 1.4 mmol, 0.1 eq.) and palladium(II) acetate (415 mg, 0.7 mmol, 0.05 eq.) in dioxane (72.1 ml, 0.2 M) was added N,N’-diisopropylethylamine (5.0 mL, 28.9 mmol, 2.0 eq.) and benzylmercaptan (2.0 ml, 17.3 mmol, 1.2 eq.). The reaction mixture was stirred at 100 C for 18 h. The reaction mixture was diluted with ethyl acetate (300 mL) and water (150 mL). The aqueous layer was extracted with ethyl acetate (150 mL). The combined organic layers were dried (Na2SO4) and concentrated under reduced pressure. The residue was purified by column chromatography.
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, 1-Benzyl-4-iodo-1H-pyrazole, other downstream synthetic routes, hurry up and to see.
