In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 16932-44-8, name is 2-Iodo-1,3-dimethoxybenzene belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. COA of Formula: C8H9IO2
General procedure: An oven dried pressure tube was charged with haloarenes (0.5 mmol), copper(II) triflate (45 mg, 0.125 mmol), KNO2 (128 mg, 1.5 mmol) and anhydrous DMSO (0.6 mL) under nitrogen atmosphere. The tube was sealed with a teflon screw cap having mininert valve and nitrogen is purged through it for 5 min. It is stirred at room temperature for 10 min and then the temperature was gradually increased to 130 oC and is maintained at the same for 48 h. The reaction mixture was then cooled to room temperature, washed with excess ice cold water and extracted with ethyl acetate (3 x 10 mL). The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to give the crude product which was purified by column chromatography using silica gel (Table 2, entries 1-18) or basic alumina (Table 2, entries 19-23) and a mixture of ethyl acetate and hexane as the eluent to afford the desired products in good yields.
The synthetic route of 16932-44-8 has been constantly updated, and we look forward to future research findings.
