Abstract

N‐Methylmorpholine N‐(^17^O‐oxide) and N‐methylmorpholine ^15^N‐(^17^O‐oxide) were prepared from N‐methylmorpholine and ^15^N‐methylmorpholine by oxidation with H~2~ ^17^O~2~. The facile one‐pot procedure provided yields of 82 and 76%, respectively. The labeled hydrogen peroxide was obtained by electrolysis of H~2~ ^17^O followed by autoxidation of 2‐ethylanthraquinol with the molecular oxygen ^17^O~2~ generated. The compounds serve for mechanistic studies into gold nanoparticle generation in NMMO solution. Copyright © 2009 John Wiley & Sons, Ltd.
