A technique is described for the acid catalyzed tritium exchange of activated aromatic protons using acetic acid-HI tritium chloride. In the two examples reported, specific activities of 0.5 Ci/rmnol were obtained for propranolol and 1.73 Ci/mmol for reserpine. be very effective and easily manipulat

## Abstract The hydrogen isotope exchange of BrefeldinβA with tritium gas (T~2~) in 1,4βdioxane was studied over a commercial palladium catalyst supported on diatomaceous earth (5% metallic weight). The effect of the gas phase was studied. Addition of air in the gas phase led to an increase of the
Commercial alumina looses some activity after the first epoxidation reaction of (S)-limonene with hydrogen peroxide, but maintains a good activity and a very high selectivity in the subsequent three reactions. After this its activity is strongly reduced, probably due to structural modifications. Alu
