Perfluoro [2( e),6( e)-dimethylpiperidin- N-oxyl]

UV irradiation of solutions of perfluoro [ N-fluoro-2( e),6( e)-dimethylpiperidine] ( 8) in the presence of oxygen and silica creates a persistent free radical with ESR spectroscopic parameters consistent with perfluoro [2( e),6( e)-dimethylpiperidin- N-oxyl] ( 7). Attempts to isolate this new oxyl...

Description
Summary:UV irradiation of solutions of perfluoro [ N-fluoro-2( e),6( e)-dimethylpiperidine] ( 8) in the presence of oxygen and silica creates a persistent free radical with ESR spectroscopic parameters consistent with perfluoro [2( e),6( e)-dimethylpiperidin- N-oxyl] ( 7). Attempts to isolate this new oxyl from products of preparative experiments in which the corresponding NON compound presumed to be formed initially had been thermolysed proved unsuccessful: only dilute solutions of the oxyl (ca. 1% yield) in (mainly) its NF precursor ( 8) were obtained.
