  Flexibly Coordinating Tris(arylamido)stannates as Ligands:  A [Rh]⁺/[Sn]^- Zwitterion as an Intermediate in the Formation of Rh−Sn Complexes

  摘要：

  Reaction of the lithium stannate MeSi{SiMe2N(3,5-xyl)}(3)SnLi(OEt2) (1) with (1)/(2) molar equiv of [RhCl(COD)](2) gave the zwitterionic heterodinuclear complex [MeSi{SiMe2N(3,5-xyl)}(2)Sn{SiMe2N(eta(6)-3,5-xyl)}Rh(COD)] (2), in which one of the peripheral N-bonded 3,5-xylyl groups acts as an eta(6)-aryl ligand to which the {Rh(COD)}(+) cation is bonded. Reaction of the 18-electron complex 2 with nucleophiles leads to an attack at the late transition element, which moves over to the tin atom to form the Rh-Sn-bonded 16-electron complexes [MeSi{SiMe2N(3,5-xyl)}(3)SnRh(L)(COD)] (L = Ph3P (3), (PhO)(3)P (4), CyNC (5)).

  square-planar complexes [MeSi[SiMe2NAryl]3SnRh(PPh3)(COD)] (Aryl = 3,5-xyl: 4a, p-tol: 4b), in which the stannates are directly bonded to rhodium through Rh−Sn bonds. Treatment of the complexes 4a,b and 5a,b with hydrogen gas in the presence of benzene leads to the hydrogenation of the diolefin and its replacement by benzene as a formal six-electron donor ligand.
