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. 13329-40-3, name is 1-(4-Iodophenyl)ethanone, A new synthetic method of this compound is introduced below., Product Details of 13329-40-3
To a solution of 4-iodoacetophcnonc 4.9 ( 1 O g, 40.6 mmol) in dioxanc ( 100 mL) was added bromine (2.18 mL, 42.7 mmol) dropwise at 0 C. The reaction mixture was stirred for 30 minutes. The resulting solution was concentrated. The residue was dissolved in dichloromethane (200 mL) and was washed with satd. NaHCO3, H2O and brine, dried over Na2SO4, and concentrated to give 4.10. To a solution of 4.10 in DMF ( 100 mL) were added potassium carbonate ( 16.8 g, 122 rnmol) and /ert-butylcarbamidine hydrochloride 4.11 ( 1 1.1 g, 81.2 mmol). After stirring overnight, the reaction mixture was filtered and the filtrate was concentrated. The resulting residue was purified on silica gel using a mixture of hexanes and ethyl acetate to give 4.12 (8.1 g, 61%). LRMS (M+Na+) m/z 327.0.
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.
