  Different bonding modes of sulfur bis-ylides in Pd complexes: Crystal structure of [Pd(μ-OAc){μ-[CH(SMe2)]2C(O)}(acac-O,O′)2]ClO4

  摘要：

  The reaction of [Me2SCH2C(O)CH2SMe2]Br-2 (1) with Pd(OAc)(2) gives the mononuclear neutral complex cis-[PdBr2(eta(2)-[CH(SMe2)](2)C(O))] (2) through double deprotonation of the bis-sulfonium salt. The sulfur bis-ylide coordinates in (2) as a C,C'-chelating ligand, and is obtained as a single diastereoisomer (meso form, RS/SR), in spite of the presence of two stereogenic ylidic centers. Reaction of (2) with AgCIO4 and Tlacac gives [Pd(acac-O,O'){eta(2)-[CH(SMe2)](2)C(O)}]ClO4 (3), which shows the same bonding mode for the bisylide ligand. However, (2) reacts with Pd(OAc)(2), AgCIO4 and Tlacac to give the dinuclear [Pd(mu-OAc){mu-[CH(SMe2)](2)C(O)}(acac-O,O')(2)]ClO4 (4) as two different isomers. In complex (4) the bis-ylide bridges two palladium atoms and the presence of two isomers arise from the relative arrangement of the bisylide with respect to the acetate ligand. The X-ray crystal structure of (4) has been determined. (C) 2008 Elsevier B.V. All rights reserved.
