Catalytic behavior of Group VIII transition metals in the deuterium-acrolein reaction
The catalytic reactions between acrolein and deuterium over all the Group VIII transition metals were studied by microwave spectrometry. A high catalyst selectivity in the exchange reaction, in which hydrogen is replaced by deuterium in acrolein, was found. Over Rh, Pd, Ir, Ru, and Ni, hydrogens situated on the ..beta.. carbon were quasi-selectively exchanged while over Pt, Os, and especially Co, an additional exchange of the aldehydic hydrogen took place. Over Fe, the hydrogen situated on the ..cap alpha.. carbon and the aldehydic hydrogen were exchanged equally. An attempt is made to relate the nature of the exchange to hydrogenation, decarbonylation, and hydrogenolysis and several reaction mechanisms are proposed in addition to the classical Horiuti-Polanyi mechanism, which is restricted to hydrogenation of the C-C double bond.
