696-82-2, 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. 696-82-2, name is 2,4,6-Trifluoropyrimidine. A new synthetic method of this compound is introduced below.
Example 1 0.5 mol of fluorine in the form of a 30% by volume mixture with helium was introduced into a suspension of 29.0 g (0.216 mol) of 2,4,6-trifluoropyrimidine, 21 g of sodium fluoride (0.5 mol) and 250 ml of trichlorofluoromethane at a temperature of -78 C. The rate of introduction was 0.15 mol of fluorine per hour. After the introduction was complete, the reaction mixture was filtered and 21.0 g of tetrafluoropyrimidine (=64% of theory) were obtained from the filtrate by distillation.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,696-82-2, 2,4,6-Trifluoropyrimidine, and friends who are interested can also refer to it.
