摘要：

A chemoselective C(sp(2))-F or C(sp(3))-F bond activation of hexafluoropropylene (HFP) was achieved by adopting the proper combination of a Lewis acid co-additive with a ligand which coordinates Pd-0. The treatment of [(eta(2)-HFP) Pd(PCy3)(2)] with B(C6F5)3 allowed a chemoselective C-(sp(3))-F bond cleavage of HFP to give a unique cationic perfluoroallypalladium complex. In this complex, the coordination mode of the perfluoroallyl ligand was considered to be of the unique eta(2)-fashion.
