## Abstract Diazepam‐^14^C and demethyldiazepam‐^14^C are synthesized from glycine‐1‐^14^C. Addition of diketene to diazepam‐^14^C leads to ketazolam‐^14^C. The reaction conditions for the formation of ketazolam from diazepam is studied using high‐pressure liquid chromatography in conjunction with
## 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
Conditions were found for almost quantitative carboxylation of n-hexyllithium with l4CO2 to afford lithium [1-l4C] heptanoate. It was then possible to perform the reaction sequence lithium [1-l4C] heptanoate --+ [l-14C] heptan-1-01 + 1-bromo [l-14q heptane in one flask without isolation of intermed
