Adding a certain compound to certain chemical reactions, such as: 454-31-9, name is Ethyl 2,2-difluoroacetate, belongs to esters-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 454-31-9, Product Details of 454-31-9

Step 2: Preparation of 4,4-difluoro-1-(3-fluoro-4-methoxyphenyl)-butane-1,3-dione. Ethyl difluoroacetate (4.06 g, 32.7 mmol) was dissolved in methyl t-butyl ether (50 mL). To the stirred solution was added 25 weight % sodium methoxide (7.07 g, 32.7 mmol) followed by 3′-fluoro-4′-methoxyacetophenone (5.0 g, 29.7 mmol). After stirring for 16 hours, 1N HCl (50 mL) was added. The organic layer was collected and washed with water (2*50 mL), dried over anhydrous MgSO4, filtered, and added to hexanes to precipitate a tan solid (7.0 g, 96%): mp 70-72 C.
