Generation of four 4-substituted o-benzynes by heterolytic fragmentation reactions is demonstrated.
ARYNIC SPECIES; EFFECT OF SUBSTITUENTS ON THE REACTIVITY OF MONOSUBSTITUTED DEHYDROBENZENES
Gavina, F.,Luis, S. V.,Costero, A. M.
, p. 155 - 166 (2007/10/02)
Evidence is presented demonstrating the existence of free dehydrobenzenes in the thermal decomposition of diaryliodonium-2-carboxylates, and that o-benzyne itself and its 4-methyl-, 4-chloro-, 4-bromo- and 4-nitro-derivatives are generated from insoluble polymer-bound precursors and trapped by a second solid phase in Diels-Alder reactions.Lifetimes for these elusive species are determined.
