Metal Complexes of Functionalized Sulfur-Containing Ligands, VI[1]. - Stabilization of 1-Alkyne-1-thiolato Ligands [R-C≡C-S-; R = SiMe3, (η5-C5H4)Fe(η5-C5H5)] in Ru(II) und Pt(II) Complexes. X-ray Structure Analysis of cis-(Ph3-P)2Pt[C≡C-(η5-C5H5)]2The 1-alkyne-1-thiolates R-C≡C-SLi [1: R = SiMe3, 3: (η5-C5H4)Fe(η5-C5H5)] react with (Ph3P)2PtCl2 and CpRu(PPh3)2Cl to give the complexes trans-(Ph3P)2Pt(S-C≡C-SiMe3)2 (4a), CpRu(PPh3)2(S-C≡C-SiMe3) (4b), and cis-(Ph3P)2Pt[S-C≡C-η5-C5H4)Fe(η5-C5H5)]2 (5). The Pt(II) bis(acetylide) complex cis-(Ph3P)2Pt[C≡C-(η5-C5H4)Fe(η5-C5H5)]2 (6a) was isolated after chromatography of 5. The trans-configurated compound 6b is obtained by the reaction of [LiC≡C-(η5-C5H4)]Fe(η5-C5H5) with (Ph3P)2PtCl2. The complexes are characterized by IR, 1H-, 13C-, and 31P-NMR spectroscopy, FAB mass spectrometry and X-ray diffraction (6a).
