What is Trifluoromethyl iodide?
Chemical properties
colourless gas
The Uses of Trifluoromethyl iodide
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.
The Uses of Trifluoromethyl iodide
