Trifluoromethylisocyanide is the chemical compound with the formula CF₃NC. It is an isocyanide and a fluorocarbon. Polymerisation occurs even at temperatures below its boiling point of -80°C. As a ligand in coordination chemistry, this species behaves similarly to carbon monoxide. [cite journal| author=D.
