Trifluoromethyl iodide Chemical Properties,Uses,Production
Chemical Properties
colourless gas
Uses
Trifluoroiodomethane is used as a gaseous fire suppression flooding agent for in-flight aircraft and electronic equipment fires. It is also an important raw material and intermediate used in organic synthesis, pharmaceuticals and agrochemicals. It is involved in the rhodium-catalyzed alfa-trifluoromethylation of alfa,beta-unsaturatedketones. It plays an important role as catalyst in the enantioselective alfa -trifluoromethylation of aldehydes through photoredox organocatalysis using a readily available iridium photocatalyst.
Preparation
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%.
