Adding some certain compound to certain chemical reactions, such as: 1190-39-2, name is malonic acid dibutyl ester, 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 1190-39-2. 1190-39-2
General procedure: PhIO (550 mg, 2.5 mmol), Et3N¡¤5HF (800 mg, 4 mmol), and DCE (1 mL)were placed in a Teflon test tube. After stirring at r.t. for 15 min, the appropriate malonic ester 1 (1 mmol) and DCE (1 mL) were added. The test tube was sealed with a septum rubber and heated at 70 C for 24 h with stirring. The reaction mixture was neutralized with aq NaHCO3 and the product was extracted with CH2Cl2 (3 ¡Á 10 mL). The combined organic layers were washed with brine (20 mL), dried (Na2SO4), and concentrated under reduced pressure. The product was purified by column chromatography on silica gel with hexane-CH2Cl2 as eluent.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of malonic acid dibutyl ester.
