Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 4090-55-5, name is 2-Chloro-5,5-dimethyl-1,3,2-dioxaphosphorinane 2-oxide, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 4090-55-5
The flask accommodating the post-reaction solution containing intermediate 4 was filled with 121.4 g (1.2 mol) of triethylamine and 1.85 g (0.015 mol) of 4-(dimethylamino) pyridine. While the mixed solution was stirred, a mixed solution of 164.2 g (0.89 mol) of material 1 and 450 g of toluene was added thereto at 20C over 2 hours. After that, the substances were reacted at the same temperature (20C) for 8 hours. The obtained post-reaction solution was neutralized at room temperature using an aqueous solution of hydrochloric acid in an amount corresponding to the excess amount of triethylamine. The resultant solution was kept still so as to be separated into different layers. Then, the organic layer was neutralized using an aqueous solution of sodium hydrogen carbonate. The organic layer was then washed with water twice. The obtained organic layer was dried by anhydrous magnesium sulfate. The solvent and water were removed by distillation, thereby obtaining 311.2 g of phosphorus compound (3). Phosphorus compound (3) had a purity measured by GPC (gel permeation chromatography) of 95.1% by area. The yield was 94.0%.
According to the analysis of related databases, 4090-55-5, the application of this compound in the production field has become more and more popular.
