Deprotonation of the trifluoroacyl hydride complex 1 with tert ‐butyllithium leads to difluoroketene adduct 2 . Coordination of the difluoroketene to iridium through the CC bond is confirmed by X‐ray diffraction (see scheme). This complex is the first isolated and characterized dihaloketene complex and provides the only structural data for difluoroketene.
