Abstract
Microwave spectroscoy has been used to locate the position of the deuterium atoms in the products from the exchange of propene with either deuterium or deuterium oxide on a series of oxide catalysts. The evidence suggests that the main intermediates are carbonium ions on zirconia and untreated tin-antimony oxide, σ-allyl species on gallium oxide, propen-1-yl and to a lesser extent propen-2-yl and σ-allyl on γ-alumina, probably π-allyl on titania and magnesia, and both allyl species on used tin-antimony oxide. A very rapid double-bond shift reaction is believed to occur on magnesia at 200 K.Keywords
