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.
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. 460-37-7, name is 1,1,1-Trifluoro-3-iodopropane, A new synthetic method of this compound is introduced below., HPLC of Formula: C3H4F3I
Zn/Cu couple (0.6 g, 9.23 mmol), 1,1,1-trifluoro-3-iodopropane (1.37 g, 6.11 mmol, Aldrich), benzene (16 mL), and N,N-dimethylformamide (1 mL) were heated together for 3 hr at 60 C. under N2. The t-butyl ester pyran from Part A (1.0 g, 2.04 mmol) and [1,1?-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with CH2Cl2 (1:1) (0.083 g, 0.102 mmol, Aldrich) were added, and the resulting dark mixture was stirred overnight at 69 C. under N2. Zn/Cu couple (0.6 g, 9.23 mmol), 1,1,1-trifluoro-3-iodopropane (1.37 g, 6.11 mmol, Aldrich), benzene (16 mL), and N,N-dimethylformamide (1 mL) were heated together for 3 hr at 60 C. under N2. This mixture was added to the original flask, and the resulting mixture was stirred overnight at 70 C. under N2. An additional portion of the Pd catalyst (same amount used above) was added to the mixture, and the resulting mixture was stirred at 70 C. overnight under N2. Zn/Cu couple (0.6 g, 9.23 mmol), 1,1,1-trifluoro-3-iodopropane (1.37 g, 6.11 mmol, Aldrich), benzene (16 mL), and N,N-dimethylformamide (1 mL) were heated together for 3 hr at 60 C. under N2. This mixture was added to the original flask along with another portion of the Pd catalyst (same amount used above), and the resulting mixture was stirred overnight at 70 C. under N2. The mixture was allowed to cool to ambient temperature, and 50 mL each of saturated NH4Cl(aq) and deionized water were added to the mixture. The mixture was then stirred for 15 min. Afterward, the mixture was further diluted with 200 mL of ethyl acetate and filtered through a pad of Celite . The filter cake was washed with 50 mL each of deionized water and ethyl acetate. The layers were separated, and the organic layer was washed with 100 mL of saturated NaCl(aq), dried over MgSO4, and concentrated in vacuo to form a brown oil (1.43 g). Chromatography (silica, ethyl acetate/hexanes) afforded 0.80 g (78% yield) of a yellow oil.
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.
