Metallkomplexe mit funktionalisierten Schwefelliganden, I / Metal Complexes of Functionalized Sulphur Containing Ligands, I

Abstract

Complexes of the types cis-L2PtCl2 (L = PPh3, 1/2 dppe) and cpRu(PPh3)2Cl react with 1-alkyne-1-thiolates to give the products trans-(Ph3P)2Pt(S–C≡C–Ph)2 (5), dppePt(S–C≡C–Ph)2 (6) and CpRu(PPh3)2(S–C≡C–Ph) (7), respectively. CpRu(PPh3)(CO)(S–C≡C–Ph) (8) is formed by reaction of 7 in an atmosphere of CO. The 2-propene-1-thiolato complexes dppePt(S–CH2–CH = CH2)2 (9), CpFe(CO)2(S–CH2–CH=CH2) (12) and CpFe(PPh3)(CO)(S–CH2–CH=CH2) (13) are obtained from dppePtCl2, CpFe(CO)2I, CpFe(PPh3)(CO)I and lithium or sodium 2-propene-1-thiolate. The complexes are characterized by IR and 1H,13C and 31P NMR spectroscopy.
