Hydrometalation of fluoroallenes

Moritz F. Kühnel and Dieter Lentz

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.
