✦ Synopsis
Vinylic C-F Bond Activation with Low-Valent Zirconocene: The Generation and Cross-Coupling Reactions of 1-Fluorovinylzirconocene. -Depending on the functional group Y, difluoroolefins (I) react with low valent Cp 2 Zr, generated in situ from Cp 2 ZrCl 2 and BuLi, to give a solution of either intermediate (E)-1-fluorovinylzirconocene or 2,2-difluorovinylzirconocene, the precursors of (III) or (IV), respectively. Reaction of the dimethylaminophenyl derivative (Id) with further aryl iodides results in formation of olefins (VI). -
