Titanium-Catalyzed C-F Activation of Fluoroalkenes

Detox: Air‐stable titanocene difluoride efficiently catalyzes the chemoselective hydrodefluorination of fluoroalkenes at room temperature leading to hydrofluoroalkenes in high yields (see scheme: Cp=cyclopentadienyl). This is a rare example of the catalyzed conversion of fluoroalkenes into less‐fluo...

Description
Summary:Detox: Air‐stable titanocene difluoride efficiently catalyzes the chemoselective hydrodefluorination of fluoroalkenes at room temperature leading to hydrofluoroalkenes in high yields (see scheme: Cp=cyclopentadienyl). This is a rare example of the catalyzed conversion of fluoroalkenes into less‐fluorinated compounds, which have a lower climatic impact, and is a potential method for breaking down toxic perfluoroalkenes.
