Reactions of alkenols with cis-Pt(Cl)2(TPPTS)2 (TPPTS = P(m-C6H4SO3Na)3) in water result in [Pt(η3-allyl)(TPPTS)2]+ as the exclusive platinum product with 1 equiv of oxidized alkenol. The η3-allyl is not fluxional in water, and the syn and anti isomers can be distinguished at room temperature. For 3-buten1-ol and 4-penten-1-ol, in addition to the η3-allyl complex and oxidation of the alkene, catalytic isomerization of the alkene is observed. No reaction occurs for cis-Pt(Cl) 2(P(p-tolyl)3)2, cis-Pt(Cl)(THF)-(P(p-tolyl) 3)2+, or cis-Pt(THF)2(P(p-tolyl) 3)22+ with the alkenols in THF, indicating the importance of H2O. Excess Cl- inhibits the reaction. The oxidation product is selectively deuterated. These observations are combined into a proposed mechanism.
