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. 128140-82-9, name is 1-(Difluoromethoxy)-4-iodobenzene, A new synthetic method of this compound is introduced below., SDS of cas: 128140-82-9
A mixture of 1-(difluoromethoxy)-4-iodobenzene (1.35 g, 5.00 mmol, 1.00 equiv), 4,4,5,5- tetramethyl-2-(tetramethyl- 1,3 ,2-dioxaborolan-2-yl)- 1 ,3,2-dioxaborolane (1.413 g, 5.56 mmol, 1.10 equiv), AcOK (1.47 g, 14.98 mmol, 3.00 equiv), and Pd(dppf)C12 (186 mg, 0.25 mmol, 0.05 equiv) in dioxane (30 mL)/ water(3 mL) was stirred for 2 h at 95C under nitrogen. The mixture was diluted with water and extracted with ethyl acetate. The combined extracts were washed with brine, dried over anhydrous sodium sulfate, and concentrated under vacuum. The residue was purified by a silica gel column eluting with ethyl acetate/petroleum ether (1:50) to afford the title compound (660 mg, 49%) as colorless oil.
The synthetic route of 128140-82-9 has been constantly updated, and we look forward to future research findings.
