Abstract

Labeled silver carbonate was prepared from barium carbonate‐^13^C or ‐^14^C and aqueous silver nitrate in 95 to 100% yield. Diethyl carbonate‐^13^C or ‐^14^C was generated in 60 to 85% overall yield by treatment of labeled silver carbonate with ethyl iodide and tetraethylammonium iodide in dimethylformamide. The effects of alterations in reaction time, metal ion, solvent and catalyst were investigated.

## Abstract A synthetic procedure for C‐14‐labeled N‐methyl‐N‐nitrosoaniline is presented. Separate labeling of the methyl and phenyl side chains was achieved by using C‐14‐labeled methyl iodide and aniline, respectively. The overall yield of the four reactions was 62% and the final products were s

## Abstract ^13^C‐ and ^14^C‐uniformly labelled catechol was synthesized from phenol in three steps. Phenol was derivatized with 2‐chloro‐5‐nitrobenzophenone in THF containing NaH, followed by __ortho__‐hydroxylation with 35% aqueous H~2~O~2~ in sulphuric acid/glacial acetic acid solution, and by c
