Description

The kinetics of hydrogen-tritium isotope exchange reaction in the presence of metallic catalysts is studied theoretically by SCF-MO CNDO/2 method. The calculated sequence of difference of substitution actived energy on the π-complex compounds formed between the tetramethyl-pyrazine and the metallic catalysts (Pd, Pt, and RhCl3) is as follows: Pd<Pt<RhCl3. It is in agreement with that obtained by Wilzbach method. Two mechanisms of reactions, namely, the associative and the dissociative π-complex mechanisms, are discussed for H-T exchange in the presence of a metal catalyst
