Adding a certain compound to certain chemical reactions, such as: 461-17-6, name is 1,1,1-Trifluoro-4-iodobutane, belongs to iodides-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 461-17-6, Formula: C4H6F3I

250g gamma-butyrolactone, 62.5g (440mmol) potassium 4-hydroxybutyrate, and 95.2g (400mmol) 4,4,4-trifluorobutyliodide were placed in a 500ml four-necked flask equipped with a stirrer, a reflux cooler, and a thermometer. By heating, the mixture was maintained at 75C for 5 hours while being stirred. At this point, it was determined by a gas chromatography that 98.6% of the 4,4,4-trifluorobutyliodide had been converted. Subsequently, the temperature was raised to 140C and the reaction was allowed to continue for another 2 hours. Upon completion of the reaction, the mixture was again analyzed by a gas chromatography. The results of the analysis revealed that 4,4,4-trifluorobutyliodide was converted at 100% conversion rate, and the selectivity for 4,4,4-trifluorobutanol, trifluorobutyl 4-hydroxybutyrate, and 4,4,4-trifluoro-1-butene were 86.5%, 13.3%, and 0.2%, respectively. The reaction mixture was then subjected to distillation: it was transferred to a 500ml flask equipped with a Claisen connector tube and a Liebig’s cooling tube, and was distilled at 120 to 140C under a pressure of 20 to 6kPa while the degree of vacuum was increased over a 3-hour period. As a result, 70.4g distillate was collected containing 49.2g (96.0% yield) of 4,4,4-trifluorobutanol. The gas chromatography analysis performed on the solution remaining in the flask indicated that it contained 0.8% trifluorobutyl 4-hydroxybutyrate

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1,1,1-Trifluoro-4-iodobutane, other downstream synthetic routes, hurry up and to see.
