RADICAL NUCLEOPHILIC SUBSTITUTION MECHANISM IN THE REACTIONS OF ARENEDIAZONIUM CATIONS WITH NITRITE ION
Singh, P. R.,Kumar, Ramesh,Khanna, R. K.
, p. 5191 - 5194 (1982)
Reactions of arenediazonium cations with nitrite ion generally believed to involve nucleophilic displacement have been found to occur via single electron transfer where free radicals intervene.
