Trifluoromethyl iodide synthesis

14synthesis methods
A glass flask provided with a gas outlet is filled with 80 g. (0.153 mole) of CI4 and 30 g. (0.135 mole) of IF5. The gas outlet is connected via short rubber tubes to several gas traps cooled with liquid nitrogen. Agitation of the vessel produces vigorous evolution of gas. When the reaction subsides, the system is heated for 30 min at 90-100°C. The condensate in the gas traps is then washed with 5% NaOH and fractionated. The yield is 90%. preparation of Trifluoromethyl iodide

Yield:2314-97-8 86%

Reaction Conditions:

with sodium iodide in acetonitrile at 70; for 2 h;Inert atmosphere;

Steps:

5 Example 5

In a 20 mL tube, nitrogen was pumped 3 times, 1.7 g (0.01 mol) of the substrate represented by formula (II-5) was added, 5 mL of acetonitrile, 1.7 g of NaI (0.011 mol) was added, and the temperature was raised to 70 ° C. for 2 h.After the reaction, the product was collected by cooling with liquid nitrogen to obtain 1.5 g of a product represented by formula (I-5), with a yield of about 86% and a purity of> 98%.
