On hydrogenation of the 2,6-bis(phenylhydrazone) of 2,6-diketopimelic acid with carrierfree tritium a very low specijic activity was achieved, due to the labile C-T-bonds in the a-positions. 2,6-Di~minopimelic-4-~H acid of spec. activity 790 mCilmmole was obtained by catalytic dehydrohalogenation of

✦ Synopsis
Abstract
A method for tritium labelling of jasmonic acid, ethyl dihydrojasmonate, and itaconic acid involving metal catalyzed hydrogen isotope exchange is described. The procedure is a convenient one‐step synthesis and specific activities in the range of 3 to 30 GBq/mmol were obtained.

## Abstract The pyrolysis of citric acid‐1, 5‐^14^C~2~ under controlled conditions and subsequent hydrolysis of the anhydride initially produced yields principally 2‐methylenebutanedioic acid‐4‐^14^C (citaconic acid‐^14^C), together with a minor amount of cis‐2‐methylbutenedioic acid‐4‐^14^C (citra
High specific activity methyl-butyrate-2,3-H3 and methyl-stearate-9,lO-H3 were stored for approximately three months. The self-radiolysis decomposition products were identified by means of radio-gas chromatographic methods and the isotopic dilution technique. Rather high G-values were found for the
## Abstract A new hepatoprotective agent, N‐(2‐hydroxyethyl)‐maleopimarimidyl morpholide (RU18492) has been synthesised labelled with tritium at C‐3, C‐4a, C‐10 and in the C‐isopropyl group. The incorporation of tritium relies on the acid‐catalysed isomerisation of levopimaric acid (4) to abietic a
