Three spin-labelling auxins have been synthesized by reaction of 4-oxo-2,2,6,6-tetramethylpiperidine-1-oxyl(TMPO) with p-chlorophenoxyacetic acid, 1-naphthylacetic acid and 2,4-dichlorophenoxyacetic acid respectively. The structures of the labelling auxins were confirmed by IR, ESR/MS measurements and elemental analysis. The preliminary bioassays of the compounds indicated that they retain the original plant regulating property.
