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, category: iodides-buliding-blocks
Preparation 1; 4′-Bromo-biphenyl-2-carbonitrile Combine 2-iodobenzonitrile (9. 0g, 38.5 mmol), 4-bromophenylboronic acid (10.4g, 51.8 mmol), 2M aqueous sodium carbonate (20 mL) and tetrakis (triphenylphosphine)- palladium (O) (4. 5g, 3.9 mmol) in 300 mL of dioxane and heat to 80°C under nitrogen with stirring. After 3 hours cool to room temperature and dilute with 900 mL of ethyl acetate. Wash with water (2 x 50mL), brine (1 x 50mL) and dry over sodium sulfate. Filter and evaporate to a yellow solid. Chromatograph on silica gel two times, eluting with a gradient of 100percent toluene to 1/9 ethyl acetate/toluene to give the title compound as a tan solid, 5.42 g (55percent). MS (FAB) = 257 (M) ; HPLC analysis is 95percent.
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.
