Trifluoromethylisocyanide is the chemical compound with the formula CF<sub>3</sub>NC. It is an isocyanide and a fluorocarbon. Polymerisation occurs even at temperatures below its boiling point of âÂÂ80 ðC. As a ligand in coordination chemistry, this species behaves similarly to carbon monoxide.
The compound trifluoracetonitrile (CF<sub>3</sub>CN) is an isomer to trifluoromethylisocyanide. The nitrile is more stable, as is the usual case.
