✦ Synopsis

The tritiated compounds biphenyl-2-T, -3-T and -4-T have been synthesized by catalytic reduction of the corresponding bromobiphenyls with tritium gas under mild conditions. The specificity of labelling, expressed in of total activity found at the desired position, and determined by degradation of the molecules, was 96.1 & 1.5, 99.29 _+ 0.01 and 98,68 Syntheses and degradations were similar to those described previously for tritiated p-terphenyls ). For biphenyl-3-T, a second degradation, giving more precise results, has been worked out.

Benzimidazole carbamates are thought to exert their biological activity as anthelmintics by binding to helminth tubulin. To investigate this hypothesis, the synthesis of two specifically-labelled tritlated benzimidazoles, parbendazole and oxibendazole, has been accompliahed. These labels were prepa
