Triggering redox activity in a thiophene compound: radical stabilization and coordination chemistry
The synthesis, metalation, and redox properties of an acyclic bis(iminothienyl)methene Lâ are presented. This Ï-conjugated anion displays pronounced redox activity, undergoing facile one-electron oxidation to the acyclic, metal-free, neutral radical L* on reaction with FeBr2. In contrast, reaction of Lâ with CuI forms the unique, neutral Cu2I2(L*) complex of a ligand-centered radical, whereas reaction with the stronger oxidant AgBF4 forms the metal-free radical dication L*2+
