Description
Tetramethylpyrazine is labelled with tritium by microwave discharge activation (MDA) of tritium gas. The labelled sample is hydrogenated in the presence of 0.5%Pd catalyst on alumina-silica support, and the labelled sample is partially hydrogenated to form tetramethyldihydropyrazine. Theoretical calculations (CNDO/2) show that the π-bond electron polarizability (superdelocalizability) of the Pd-pyrazine ring is greater than those of the Pt-phrazine ring, the Rh-pyrazine ring or the pyrazine ring
