## Abstract Synthesis of ^14^C‐labelled Lawsone or 2‐hydroxy‐1,4‐naphthoquinone was achieved by auto‐oxidation of [phenyl‐^14^C(U)]α‐tetralone; the latter was prepared from [^14^C(U)] benzene in a reaction sequence more convenient than reported earlier. Copyright © 2002 John Wiley & Sons, Ltd.

Abstract
The high yield, four‐step synthesis of catechol‐U‐^14^C from benzene‐U‐^14^C is described. Intermediates in the preparation include phenol‐U‐^14^C and o‐methoxyphenol‐U‐^14^C [guaiacol‐(phenyl‐U‐^14^C)].
