A Pd(II) Complex Exhibiting Tetradentate NHC-Phosphine Ligand: On Route to Unconventional Phosphonium Ylide Derivatives
Unusual open-chain tetradentate NHC-phosphine pre-ligand [Ph2PCH(Ph)ImCH2ImC(H)PhPPh2](BF4)2 was prepared in a good yield by metal-mediated approach starting from Mn(I) complex [Cp(CO)2Mn(η2-Ph2P=C(H)Ph)](BF4) and bis(imidazole) derivative ImCH2Im. Its reaction with Pd(OAc)2 afforded dicationic Pd(II) complex of bis(NHC)bis(phosphine) ligand adopting κ4PĈĈP coordination mode as a mixture of two diastereomers. The deprotonation of the C(H)Ph ligand bridge in the latter using KN(SiMe3)2 as base provided stable complex exhibiting unconventional phosphonium ylide moiety, whereas all attempts to detect the corresponding bis(ylide) derivative failed.
