The catalytic activity and reactivity of the charge-transfer complexes and the ion radical salts have been investigated by means of the ortho-parahydrogen conversion, the deuterized reaction and the hydrogen-deuterium equilibration. The predominant reaction on the aromatics-alkali metal ion salt occurred through a chemisorption mechanism. These findings were confirmed by the electrical conductivity and also the photoemission measurements of unexposed and hydrogen-exposed ion salts. Hydrogenase activity in the dry state is also discussed.
