  The reactions among halonitrobenzenes or polynitrobenzenes and alkoxides, thiolates or tertiary amines have provided the evidence that in a SNAr reaction type a single electron transfer from the nucleophile to the aromatic substrate, to generate two radical species within the solvent cage, can take place to some extent.

  When a freshly distilled tertiary alkyl amine is dissolved in water a base-catalyzed oxidative dealkylation process takes place, leading to the formation of secondary nitroxyl radicals, alkenes and carbonyl-containing compounds.

  The radical-initiated reaction of tris(trimethylsilyl)silane with a variety of aliphatic nitro derivatives has been investigated. This silane, which for many applications is a valid alternative to tributyltin hydride, is unable to reduce tertiary nitroalkanes to the corresponding hydrocarbons. EPR results, as well as kinetic and products studies, have shown that this ''anomalous'' behavior is due to the fact that the nitroxide adducts formed by addition of tris(trimethylsilyl)silyl radicals to the nitro compounds fragment preferentially at the nitrogen-oxygen bond rather than at the carbon-nitrogen bond as in the analogous tributyltin adducts. The resulting silyloxy radical, (Me3Si)3SiO+, undergoes a fast rearrangement (k greater-than-or-equal-to 10(7) s-1 at room temperature) with migration of a Me3Si group from silicon to oxygen to give (Me3Si)2SiOSiMe3 which adds to the nitro compound affording a secondary nitroxide adduct. The kinetics of the decay of both primary and secondary adducts to nitromethane has been studied over a wide range of temperatures. With tertiary nitroalkanes persistent aminyl radicals, RNOSi(SiMe3)3, have also been detected.
