Reactivity of platinum-based trinuclear carbonyl clusters of the type L2PtRu2(CO)8, where L2 = 1,3-bis(diphenylphosphino)propane (dppp) and 1,2-bis(diphenylphosphino)ethane (dppe), is described. Oxidative additi
Novel reactivity aspects of cis-bis(1-alkenyl)platinum(II) compounds of the type Pt(CH2(CH2)nCHCH2) 2L2 (where L2 = dppp, dppe, dppm and n = 1, 2)

We describe the synthesis, structure and reactivity of novel bis(1-alkenyl)platinum(II) complexes, Pt[CH2(CH2) nCHCH2]2L2 (where L2 = dppp, dppe, dppm and n = 1, 2). The stability of the title complexes with the different ligands is discussed. The steric, chelating and electronic properties of the ligands have a significant impact on the structure as well as on the reactivity of the complexes. Novel reactions with elemental sulfur and carbon dioxide are described and discussed.
Selective isomerization of cis-PtL2(1-alkenyl)2 to cis-PtL2(2-alkenyl)2 complexes

Heating the 1-alkenyl complexes cis-[Pt(1-alkenyl)2L 2] [alkenyl = 1-pentenyl, 1-hexenyl, 1-heptenyl, and 1-octenyl; L2 = 1,3-bis(diphenylphosphino)propane (dppp) or 1,2- bis(diphenylphosphino)ethane (dppe)] to 100°C caused a quantitative isomerization to the corresponding 2-alkenyl complexes cis-[Pt-(2-alkenyl) 2L2]. This novel isomerization is strongly dependent on the length of the alkenyl chains as well as the nature of the ligand, L 2. The new 2-alkenyl complexes were fully characterized by analytical and spectroscopic methods. An X-ray crystal structure of cis-[Pt(2-pentenyl) 2(dppp)] confirms this isomerization. Possible reaction mechanisms are discussed.
