## Abstract Regiospecific syntheses of tritium labelled precocene I (**5a**) and precocene II (**5b**), the antijuvenile hormones, have been accomplished. The syntheses involved condensations between 2βhydroxyacetophenones (**1**) with acetoneβT to give cross condensation products **2** which on cy
## Abstract The preparation of tritium labelled catechol by catalytic reduction of tetrabromocatechol is described. Recrystallization of catechol (Uβ^3^H) after silica gel column purification gave 68% yield of the desired product with 98% purity as assayed by high performance liquid chromatography.
## Abstract The reaction conditions for the incorporation of tritium into zaleplon have been investigated. The methods studied were the catalytic isotope exchange reaction with tritium gas and catalytic isotope exchange reaction with tritiated water. The results showed that the latter method was th
