## Abstract A selective and quantitative method was developed for a microscale preparation of 4‐thiouracil‐2‐^14^C by the direct thiation of uracil‐2‐^14^C. From pyridine, dioxane, and tetralin as the thiation solvents, the best yield was obtained in dioxane (96.6% of 4‐thiouracil‐2‐^14^C). The sim

## Abstract Carbonyl sulfide (COS) was prepared by a replacement reaction from potassium thiocyanate (KSCN) in 50% sulfuric acid. ^14^C‐COS or ^35^S‐COS can be prepared by the same method, depending on the position of the label in the starting KSCN. The yield of the final product is in excess of 60

## 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
