Synthetic Route of 34270-90-1, 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. 34270-90-1, name is 1-Iodo-2-(2-iodoethoxy)ethane belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a stirred solution of Intermediate 58 (4.3 g, 14 mmol) in anhydrous DMF (100 mL), cooled to 0C, was added cesium carbonate (14 g, 42.92 mmol). The reaction mixture was stirred at 0C for 10 minutes, then l-iodo-2-(2-iodoethoxy)ethane (4.3 mL, 29.00 mmol) was added dropwise at 0C. The reaction mixture was stirred at r.t. for 18 h, then the solvent was removed in vacuo. The brown residue was dissolved in EtOAc (100 mL) and washed with brine (3 x 30 mL). The separated organic layer was dried with sodium sulfate, and concentrated in vacuo. The resulting crude oil was purified by flash column chromatography on silica, using a gradient of 0-100% EtOAc in isohexanes, to afford the title compound (3.6 g, 68%) as a red oil. HPLC-MS (ES+) (method 5): MH+ m/z 369.0, RT 1.20 minutes.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Iodo-2-(2-iodoethoxy)ethane, other downstream synthetic routes, hurry up and to see.
