Abstract
The reactions among halonitrobenzenes or polynitrobenzenes and alkoxides, t hiolates or tertiary amines have provided the evidence that in a SNAr react ion type a single electron transfer from the nucleophile to the aromatic su bstrate, to generate two radical species within the solvent cage, can take place to some extent. The detection of radical intermediates by EPR spectro scopy, in several SNAr reactions, is reported.
