【 摘 要 】
P-Fluorous phosphine (R2PRf), in which the perfluoroalkyl group is directly bonded to the phosphorus atom, is a promising ligand because it has a hybrid functionality, i.e., electron-poor and fluorous ligands. However, examples of P-fluorous phosphine–metal complexes are still rare, most probably because the P-fluorous group is believed to decrease the coordination ability of the phosphines dramatically. In contrast, however, we have succeeded in synthesizing a series of P-fluorous phosphine–coordinated metal complexes such as rhodium, iridium, platinum, and gold. Furthermore, the electronic properties of R2PnC10F21 are investigated by X-ray analysis of PtCl2(Ph2PnC10F21)2 and the infrared CO stretching frequency of RhCl(CO)(R2PnC10F21)2. IrCl(CO)(Ph2PnC10F21)2- and AuCl(R2PnC10F21)-catalyzed reactions are also demonstrated.
