Tetrafluoroallene (1) and 1,1-difluoroallene (2) react under mild conditions with group 6 and 7 transition metal hydride complexes Cp(CO)3MoH (4), CO5MnH (5), Cp2WH2 (9), and Cp2MoH2 (10) to give the new fluoropropenyl complexes 6a, 7a, 11, 12, 15a–c, and 16a–c, which were characterized by single crystal X-ray diffraction. Complexes 6a and 7a undergo thermally induced 1,3-fluorine migration, whereas 11 and 12 show hindered rotation around the carbon metal single bond.
