spin labels have been prepared. Nitroxide mesylate 5 and p-hydroxyacetophenone gave 6 which was selectively brominated with cupric bromide to give the alkylating agent 7. The more watersoluble phenacyl bromide analogue 17 was prepared either via the route 8 → 11 → 17 or else via the route15 → 16 → 11 → 17. Preliminary results indicate that toward aconitase, nitroxide alkylating agent 17 behaves similarly
