Pt-hydroxo complex, [(COD)Pt(OH)]nn+reacts with alkenes, both acyclic and cyclic ones, to yield their oxygenatedproducts. Oxygenation of 2-norbornene yields the protonated platinaoxetane,[(COD)Pt(OH)(C7H10)]+ while ethene is oxidized to acetaldehyde. Both thesereactions are observed to be proton catalyzed. The ethene oxidation yieldsacetaldehyde and (COD)Pt(CH2CH3)(OTf) as only products.Further the reaction was seen to proceed via a Pt p-bonded intermediate whichwas characterized by 1H and 13C NMR techniques. Ananalogous situation is seen in the case of propene oxidation, where acetone isproduced. Herein we present the experimental details and proposed mechanismsfor these alkene oxidation pathways.
