Pathways for the decomposition of arenediazonium ions: the question of aryne participation
Abstract
1-Phenyl-3,3-dimethyltriazene (1; X = H) is a stable source for the benzenediazonium ion which is in eaquilibrium with the betaine (2) and hence can kgive rise to products derived from benzyne and phenyl radicals: on the other hand, the analogous 2,3,4,5-tetrahalogenophenyltriazenes (1; X = F or Cl) do not lead to arynes.
