The dication lies across a crystallographic inversion center.
2
Ready generation of radical cations was supported by cyclic voltammetry measurements, revealing stepwise formation of radical cation and dication species in solution.
3
Spectroscopic studies indicated that these radical cations and dications have good stability.
4
In substitution reactions at the phosphorus atom the triflyloxy moiety serves as a leaving group and enables the synthesis of rare examples of pseudo-halophosphonium dications.
