On the basis of catalytic deuteration of cyclic α and γ-aminoketones in 1-2N DCl/D2 or H2, in the presence of PtO2, it is assumed that the mechanism of heterogenous catalysis for both classes of compounds is ionic in character, and that the reaction takes place in the electrical double layer at the interface of solid and liquid.As a consequence of the reduction, two deuteriums (or hydrogens if HCl is used) from the reduction medium are introduced into the molecule, the catalyst only facilitating and not participating in the reaction itself.
