Reactions of alkenols with cis-Pt(Cl)2(TPPTS)2 (TPPTS = P(m-C6H4SO3Na)3) in water result in [Pt(
s/gifchars/eta.gif" BORDER=0 >3-allyl)(TPPTS)2]+ as the exclusive platinum product with 1 equiv of oxidized alkenol. The s/gifchars/eta.gif" BORDER=0 >3-allyl isnot fluxional in water, and the syn and anti isomers can be distinguished at room temperature. For 3-buten-1-ol and 4-penten-1-ol, in addition to the s/gifchars/eta.gif" BORDER=0 >3-allyl complex and oxidation of the alkene, catalyticisomerization 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 ofH2O. Excess Cl- inhibits the reaction. The oxidation product is selectively deuterated. These observationsare combined into a proposed mechanism.
