(Th'+ ClO,-), tris (p-bromopheny1) aminium hexachloroantimonate (TE! PA'+ SbClJ, and TBPA'+ SbF {. The ether and olefin products, which are formed in high yield in CH2C12/MeOH solvent, are not those expected from the usual free-radical decomposition of azoalkanes but instead implicate carbocations. Although the reaction stoichiometry clearly requires 2 equiv of cation radical salt to one of azoalkane, the mechanism is not yet clearly ...
