Abstract

Abstract : The anion derived from the "super stable" Blatter radical is unstable and transforms to two main products via a novel mechanism. Abstract : Addition of PhLi to 7-(CF3 )benzo[ e ][1, 2, 4]triazine at −78 °C gives the "super stable" Blatter radical in high yields, while above −5 °C two additional products are formed. XRD analysis revealed the formation of a "trimer" and a benzo[ f ][1, 2, 4]triazepine via a novel mechanism. The latter is formed from the anion generated from the isolated radical, which suggests its instability in organic batteries.
