Di-terf-butyl nitroxide

The photochemistry of di-terf-butyl nitroxide was studied149. When di-tert-butylnitroxide (DTBN) is excited at 254 nm to the rnt state in pentane solution, it is cleaved to terf-butyl radical and 2-methyl-2-nitrosopropane (with quantum yield of 0.21). The tert-butyl radical is scavenged by DTBN to give di-ferf-butyl-terf-butoxyamine150 (equation 129). 

A variety of persistent nitroxyl radicals such as TEMPO (2,2,6,6-tetrameth-ylpiperidine-A-oxyl) or di-terf-butyl nitroxide have been used to synthesize an array of different metal complexes, including s-block metalloids [38], early transition metals [39], and lanthanoids [40].
