## Abstract It was possible to prepare ^14^C‐2,4,2′,4′‐tetrachlorobiphenyl with a purity of 98% by condensation of ^14^C‐1‐chloro‐2,4‐dinitro‐benzene to yield ^14^C‐2,4,2′,4′,‐tetranitrobiphenyl and substitution of the nitro groups by chlorine with thionyl chloride. The synthesis must be carried ou

## Abstract A versatile method for ^14^C labeling of 2‐methoxypyrimidine‐5‐carboxylic acid at the 2‐position has been developed after encountering difficulties with traditional approaches to label the carboxyl function. The method developed can also be used for ^14^C labeling other positions of the

## Abstract A widely used herbicide, 2,2‐dichloropropionic acid (dalapon), was synthesized with ^14^C‐labeling in the C‐1 or C‐2 positions. The carboxyl labeled material was prepared in 55% yield by carbonation of 1,1‐dichloro‐ethyllithium at approximately −104°. Starting with trichloroacetic acid,
