Trifluoroethylation made easy: The ease of execution of the reaction (see scheme), which runs under mild conditions and without the need for additional base or ligands, allows for the rapid parallel synthesis of a broad variety of trifluoroethylated alkynes. Both experimental and theoretical analyses indicate that the trifluoromethylcarbene could undergo concerted insertion into the CspH bond of the alkyne.
