Reference of 624-76-0,Some common heterocyclic compound, 624-76-0, name is 2-Iodoethanol, molecular formula is C2H5IO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
(a) Synthesis of compound (m-2) Under a nitrogen atmosphere, a three-necked flask equipped with a stirrer chip and a dropping funnel was charged with 20.9 g (200 mmol) of the compound (m-1), which was dissolved in 160 ml of dichloromethane. The dichloromethane solution was cooled to 0C and 30.4 g (300 mmol) of triethylamine was added, followed by further stirring. After adding 37.8 g (220 mmol) of ethanol diiodide dropwise over 30 minutes, the reaction solution was heated to room temperature and stirred for two hours. After the reaction, the reaction solution was added to 300 ml of saturated ammonia chloride water and the dichloromethane layer was extracted using a separating funnel. The remaining water layer was extracted twice with 200 ml of dichloromethane. After removing the solvent from the collected dichloromethane layer, the residue was separated using column chromatography to obtain a compound (m-2).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Iodoethanol, its application will become more common.
