Synthesis and Characterization of Platina-β-diketones

Hexachloroplatinic acid reacts with n-butanol to give the but-2-ene complex H[PtCl3(η2-C4H8)] (3) as intermediate, which reacts with trimethylsilyl-substituted acetylenes R‘C⋮CSiMe3 (R‘ = H, Me, SiMe3) with cleavage of the silyl groups to form platina-β-diketones [Pt2(μ-Cl)2{(COR)2H}2] [R = Me (2a),...

Description
Summary:Hexachloroplatinic acid reacts with n-butanol to give the but-2-ene complex H[PtCl3(η2-C4H8)] (3) as intermediate, which reacts with trimethylsilyl-substituted acetylenes R‘C⋮CSiMe3 (R‘ = H, Me, SiMe3) with cleavage of the silyl groups to form platina-β-diketones [Pt2(μ-Cl)2{(COR)2H}2] [R = Me (2a), Et (2b)]. The constitution of 2 was determined by microanalysis, NMR (1H, 13C) spectroscopy, IR, Raman, and mass spectroscopy. The structure of 2a was determined by X-ray diffraction.
