Adding a certain compound to certain chemical reactions, such as: 4387-36-4, name is 2-Iodobenzonitrile, belongs to iodides-buliding-blocks 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 4387-36-4, Formula: C7H4IN
0.25 mmol of 2-cyanoiodobenzene, 0 l of the cyanide reagent K4 [Fe (CN) 6] was added to a 25 mL screw test tube, Sodium acetate 0.25 mmol, 100 mg 3 wtpercent Pd / Ce ?, and then 7 mL of N, N-dimethylformamide and lmL isopropanol Organic solvent to test tube, 500W visible light irradiation under the magnetic stirring reaction, control visible light intensity of 0.74W / cm2, anti Should be the temperature of 65 ° C, 10 hours after the reaction to stop the reaction, take a small amount of reaction solution by microporous membrane filtration, methanol solvent dilution And the liquid sample to be tested, the sample to be tested with 2-cyanide iodobenzene standard, phthalonitrile standard for high-performance liquid phase detection comparison The selectivity of the reaction product was 94.1percent, the selectivity of the target product was 49.7percent, and the liquid product yield was 46.8percent. Rear Processing method for the use of cloth funnel filter washing catalyst, drying for recycling use; reaction solution by dichloromethane and water After the mixed solution was extracted, the organic layer was concentrated and the final product phthalonitrile was obtained by column chromatography. The isolated yield was 42percent
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, 2-Iodobenzonitrile, other downstream synthetic routes, hurry up and to see.
