17O-Labelled aminyloxides 4 and 7 have been prepared either by direct reaction of the intermediate aminyl radicals 3 and 6 generated by various methods, with 17O-enriched oxygen, or by spin trap reactions performed with 17O-labelled 2-methyl-2-nitrosopropane (8) and 2-methyl-2-nitropropane (13) respectively. Reaction of 17O-labelled tert-butylhydroxylamine with phosgen yielded 11 which was transformed

The radicals (Et3Si)2N·, Me3SiNBut, and ButMe2SiNBu2 have been generated photochemically and studied using e.s.r. spectroscopy; previous assignments of spectra to the first two radicals appear to be incorrect.
