201138-91-2, Adding some certain compound to certain chemical reactions, such as: 201138-91-2, name is 4,6-Dibromodibenzo[b,d]furan, 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 201138-91-2.
In a innert atmoshphere pubchem (http://pubchem.ncbi.nlm.nih.gov/) 4,6-dibromodibenzofuran(4,6-dibromodibenzofuran) 100g (307mmol) in dimethylformamide (DMF) and then dissolved in 0.9 L, here bis(pinacolato)diboron (bis (pinacolato)diboron) 78.0g (307 mmol) and (1,1′-bis (diphenylphosphine) ferrocene) palladium dichloride (II) (1,1′-bis (diphenylphosphine) ferrocene) dichloropalladium (II)), 2.51g (3.07 mmol), potassium acetate and 90.4g (921 put mmol) was heated to reflux at 100 for 3 hours. After the reaction was completed, the reaction solution into water and then filter the mixture, and dried in a vacuum oven. Thus the resulting residue was separated and purified by flash column chromatography gave Compound I-2 56.1g (49%)
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 201138-91-2.
