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. 624-75-9, name is 2-Iodoacetonitrile belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Computed Properties of C2H2IN
General procedure: Starting amine (5.0 mmol) was dissolved in dry diethyl ether (17 mL) and iodoacetonitrile (5.5 mmol, 919 mg) was added dropwise under cooling. The mixture was stirred at room temperature for 3-14 days, then precipitate was filtered off, washed with diethyl ether and dried in vacuo to give the corresponding quaternary ammonium salt 2. If the solid precipitate was not formed after 7 days, the mixture was evaporated under reduced pressure. The crude product was washed with diethyl ether (3 ¡Á 15mL) and dried in vacuo. The quaternary ammonium salt 2 was used in the next step without additional purification. The corresponding quaternary ammonium salt (3.0 mmol) was heated at 150 C on oil bath in freshly distilled DMF (7 mL) in a 25 mL round-bottom flask fitted with reflux condenser and CaCl2-tube for 15 minutes. The mixture was cooled to room temperature, diluted with H2O (20 mL) and extracted with PhMe (2 ¡Á 15mL). The organic phase then was washed with H2O (2 ¡Á 15mL) and brine (15 mL), dried over Na2SO4 and evaporated in vacuo to give the desired aminoacetonitrile 4. The latter, if necessary, was purified by column chromatography (it is convenient to visualize aminoacetonitriles on TLC-plate by treating with the diluted solution of ninhydrin in EtOH). Note, that aminoacetonitriles are moisture sensitive. Products after column chromatography were additionally dried by the addition of dry PhMe (5 mL) and evaporation in vacuo.
The synthetic route of 624-75-9 has been constantly updated, and we look forward to future research findings.
