Abstract
Hexachloroplatinic acid reacts with n-butanol to give the but-2-ene co mplex H[PtCl3(eta(2)-C4H8)] (3) as intermediate, which reacts with tri methylsilyl-substituted acetylenes R'C=CSiMe(3) (R' = H, Me, SiMe(3)) with cleavage of the silyl groups to form platina-beta-diketones [Pt-2 (mu-Cl)(2){(COR)(2)H}(2)] [R = Me (2a), Et (2b)]. The constitution of 2 was determined by microanalysis, NMR (H-1, C-13) spectroscopy IR, Ra man, and mass spectroscopy. The structure of 2a was determined by X-ra y diffraction.
