Abstract
Pentachloronitrobenzene‐^14^C~6~ was synthesized in 81.7% yield by exhaustive chlorination of nitrobenzene‐^14^C~6~. Hexachlorobenzene‐^14^C~6~ was produced in 11% yield as a byproduct of the reaction.

14C labelled Metribuzine was synthetised in a five step synthesis firom sodium [l-14C]pivalate (trimethyl acetic acid) via o-brom0-[2-~~C]pinacoline (l-bromo-3,3-dimethyl-butan-2-on) and trimethyl [2-14C]pyruvic acid. The total yield was 30% (calculated on sodium pivalate).
## Abstract Hexazinone ‐ a s‐triazine type contact herbicide ‐ was labelled with ^14^C for the investigation of metabolic pathways. A convenient synthesis was elaborated for labelling of the carbon atom in the 6 position of the triazine ring. The molar activity of Hexazinone was 797.0 MBq/mmole (21
## Abstract A small‐scale synthesis of 1,5,9‐cyclododecatriene‐x‐^14^C~6~ is described. 1,3‐Butadiene‐1,4‐^14^C~2~, specific activity of 1.15 mCi/mmole, was prepared via the thermal decomposition of tetramethylene‐1,4‐^14^C~2~‐bis‐(trimethylammonium hydroxide) and immediately converted to a mixture
## Abstract 6‐n‐Propyl‐2‐thiouracil‐6−^14^C was prepared from sodium butyrate‐1−^14^C, with a radiochemical yield of 34%. Butyryl chloride‐1−^14^C was prepared from butyric acid‐1−^14^C and condensed with sodio ethylacetoacetate to yield ethyl β‐oxohexanoate‐β−^14^C. The β‐keto ester was condensed
