Indirect reduction of derivates of tert-butyl hydroperoxide by means o
f aromatic radical anions in DMF results in the formation of tert-buto
xy radicals, which abstract a hydrogen atom from DMF. The N,N-dimethyl
aminocarbonyl radical may couple with the radical anion or be reduced
by it; from this competition the reduction potential of the N,N-dimeth
ylaminocarbonyl radical is estimated to be -1.62 V (SCE).
