The Mechanism of Hydrogenolysis and Isomerization of Oxacycloalkanes on Metals, Part X. Nature of the Active Sites in the Regioselective Hydrogenation of Oxiranes

Summary The hydrogenolysis and isomerization of methyloxirane were studied over various Pt catalysts in order to determine the number and nature of the active sites. The steps were found to be the probable active sites and the transformation is structure-sensitive. The regioselectivity is not affected by variation in the catalyst structure, so it is determined by the nature of the metal.
