4-Dioxo-3,3-Pentanediselenolato(Se2-ac) platinum(II) complex [Pt(Se2-ac)(PMe2Ph)2] and its dithiolato analog [Pt(S2-ac)(PMe2Ph)2] have been prepared by treating cis-[PtCl2(PMe2Ph)2] with 2,3-diseleno-1,1,4,4,-tetraacetylbutane and 2,3-dithio-1,1,4,4-tetraacetylbutane in a KOH/acetone–methanol mixed solution. The IR, 1H, 13C, and 31P NMR and mass spectra of these complexes are discussed.
Synthesis and Characterization of a 3-Thio-2,4-pentanedionate Pt(II) Complex; Bis(dimethylphenylphosphine)[2,4-pentanedione-3-thiolato(2−)-<i>O</i>,<i>S</i>]-platinum(II) Prepared by S–S Bond Cleavage of 2,3-Dithio-1,1,4,4-tetraacetylbutane
3-Thio-2,4-pentanedionate (tac) complex of platinum(II), [Pt(tac)(PMe2Ph)2], has been prepared by treating [PtCl(PMe2Ph)3][PF6] with 2,3-dithio-1,1,4,4-tetraacetylbutane in a KOH/methanol–acetone mixed solution. This complex has been characterized by IR, 1H, 13C, and 31P NMR, secondary ion mass and ESR spectroscopy and cyclic voltammetry.
