We report the synthesis of tetrameric Cu(i) and Ag(i) homoleptic complexes supported by the tris(piperidinyl)imidophosphorane [NP(pip)] and [NP(1,2-bis-Bu-diamidoethane)(NEt)] ligands. These complexes demonstrate the redox stability of the imidophosphorane ligands to oxidizing salts, and the silver complexes can, in turn, serve as oxidative transmetallation reagents for the isolation of tetravalent cerium complexes from cerium metal or trivalent cerium precursors.
我们报道了由三（哌啶基）亚氨基膦烷[NP(pip)]和[NP(1,2 - 双丁基二氨基乙烷)(NEt)]配体支持的四聚体Cu(i)和Ag(i)同配物的合成。这些配合物证明了亚氨基膦烷配体对氧化盐的氧化还原稳定性，并且银配合物进而可以作为氧化转金属试剂，用于从金属铈或三价铈前体中分离四价铈配合物。
