摘要

Abstract Diazotization of 4-amino-2, 2, 6, 6-tetramethylpiperidine in acetic or sulfuric acid affords 2, 2, 6, 6-tetramethyl-1, 2, 3, 6-tetrahydropyridine in high yield. Under the same conditions, the corresponding nitroxyl radical transforms into 4-hydroxy-2, 2, 6, 6- tetramethylpiperidine-1-oxyl.
