Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 689260-53-5, name is 2-Bromo-5-iodo-1,3-dimethylbenzene, A new synthetic method of this compound is introduced below., HPLC of Formula: C8H8BrI
A flask charged with a stir bar, 2-bromo-5-iodo-1 ,3-dimethyl-benzene (1 .0 g), bis- (pinacolato)-diboron (1 .0 g), potassium acetate (1 .1 g) and dimethyl sulfoxide (10 ml_) is purged with argon for 5 min. [1 ,1 ‘-Bis(diphenylphosphino)-ferrocene]- dichloropalladium(ll) (0.26 g) is added at room temperature, and the mixture is stirred at 90 C for 3 h. After cooling to room temperature, water is added and the resulting mixture is extracted with ethyl acetate. The combined extracts are dried (MgSO4) and concentrated. The residue is chromatographed on reversed phase (HPLC; acetonitrile/water) to give the title compound . LC (method 9): tR = 1 .30 min; Mass spectrum (ESI+): m/z = 31 1/313 (Br) [M+H]+.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
