Zirconium-mediated carbon–fluorine bond functionalisation through cyclohexyne “umpolung”​

Polarity reversal, or “umpolung”, is a widely acknowledged strategy to allow organic functional groups amenable to react in alternative ways to the usual preference set by their electronic features. In this dataset, we collect all our multi-nuclei NMR data that sustain the demonstration that cyclohexyne umpolung, realized through complexation to zirconocene, makes the small strained cycloalkyne amenable to C–F bond functionalisation.
