Hydrometalation of fluoroallenes.
Tetrafluoroallene () and 1,1-difluoroallene () react under mild conditions with group 6 and 7 transition metal hydride complexes Cp(CO)(3)MoH (), CO(5)MnH (), Cp(2)WH(2) (), and Cp(2)MoH(2) () to give the new fluoropropenyl complexes , , , , , and , which were characterized by single crystal X-ray diffraction. Complexes and undergo thermally induced 1,3-fluorine migration, whereas and show hindered rotation around the carbon metal single bond.
