摘要：

Reactions of alkenes (ethylene, propene, and 1-hexene) With water in the presence of cisPt(Cl)(2)(TPPTS)(2)(TPPTS = P(m-C6H4SO3Na)(3)) produces stoichiometrically the Wacker oxidation product (acetaldehyde, acetone, and 2-hexanone, respectively) and trans-Pt(Cl)-(H)(TPPTS)(2). The presence of the phosphine ligands provides stability to the hydride complex such that decomposition to the metal is prevented. For C2H4 the final product is trans-Pt-(Cl)(C2H5)(TPPTS)(2). These reactions are fully consistent with the PdCl42- oxidation of alkenes. At higher temperatures, however, C2H4 is catalytically oxidized to CH3CHO in a mechanism that appears to be different. At 95degreesC, 90 turnovers are observed.
