Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 460-37-7, name is 1,1,1-Trifluoro-3-iodopropane, A new synthetic method of this compound is introduced below., Recommanded Product: 460-37-7
A solution of 2.0 g (5.95 mmol) of the compound from Ex. 21 A in 40 ml DMF was added 1.39 g (13.1 mmol) of cesium carbonate and stirred for 15 min at RT.Then 2.66 g (11.9 mmol) 3,3,3-trifluoro-1-iodopropane were added, and the mixture was heated to 60 C.After 1 hour, additional 2.66 g (11.9 mmol) 3,3,3-trifluoro-1-iodopropane added.Stirring at 60 C was continued for 16 hours.After cooling to RT was treated with about 160 ml of water supply and is extracted three times with 80 ml of diethyl ether.The combined organic extracts were washed with saturated sodium chloride solution.After drying over anhydrous magnesium sulfate, was filtered and evaporated.The crude product was purified by MPLC on a Puriflash cartridge (100 g silica gel, cyclohexane / ethyl acetate 7: 1-> 1: 1).The product fractions were combined, evaporated and the residue dried under high vacuum.There were 1.86 g (72% d. Th.) Of the title compound.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
