Abstract
A 20.4 mCi sample of 99% radiochemically pure 3,6‐dichloropicolinic acid‐2,6‐^14^C with a specific activity of 11.6 mCi/ mmole was synthesized via a five step process from glutarimide‐ 2, 6‐ ^14^C.

## Abstract An 88.6% yield of 2,3,5,6‐tetrachloropyridine‐2,6‐^14^C (8.99 mCi, 14.5 mCi/mmole) was obtained __via__ chlorination of 2,6‐dichloropyridine‐2,6‐^14^C.
Residues of clopyralide in strawberries treated with herbicide preparation Lontrel 300 were determined using gas chromatographic method. The decrease of clopyralide content during the processing of contaminated fruits was observed. The rate of decomposition of this compound in model solutions (held
## Abstract In a first step, Δ1‐trans‐octenoic‐3‐^14^C acid was prepared by a Grignard reaction with BaCO~3~‐^14^C and 1‐bromo‐pentane, followed by reduction of the obtained hexanoic‐1‐^14^C acid to hexanal‐1‐^14^C via the n‐hexanol‐1‐^14^C. The produced hexanal‐1‐^14^C, by condensing with malonic
## Abstract Pentachloropyridine serves as a key intermediate in the synthesis of 4‐amino‐3,5,6‐trichloropicolinic acid (picloram) and 4‐amino‐3,6‐dichloropicolinic acid (aminopyralid). An M+3 stable isotope of pentachloropyridine (1, pentachloropyridine‐1‐^15^N‐2,6‐^13^C~2~) was prepared from K^13^
6-14C]Nitrendipine synthesis started from barium[14]carbonate, which was converted to [ 1-14C] acetyl chloride. The acid chloride was condensed with Meldrum's acid (2,2-dimethyl-1,3-dioxane-4,6-dione). The resulting intermediate was treated with boiling methanol to give methyl [ 3-14C]acetoacetate.
